The 2 TB Family Plan at $9.99/month ($119.88/year)
The price is fixed for your current plan. But if you run out of space and upgrade (e.g., from 200GB to 2TB), the new fixed price applies immediately, prorated for the remainder of your billing cycle. Google does not penalize you for upgrading, but you cannot downgrade mid-cycle.
If you are currently on a Google One Family Plan and want to confirm your locked-in price, follow these steps:
Red flags to watch for:
Google offers three primary tiers that support family sharing. Note: The basic 100GB plan does exist, but it does not support family sharing. To get the "Family Plan" features, you must start at the 200GB tier or higher.
| Storage Tier | Family Sharing Supported? | Monthly Fixed Cost | Annual Fixed Cost (Save ~16%) | | :--- | :--- | :--- | :--- | | 100 GB | No (Individual only) | $1.99 | $19.99 | | 200 GB | Yes | $2.99 | $29.99 | | 2 TB | Yes | $9.99 | $99.99 | | 5 TB | Yes | $24.99 | $249.99 | | 10 TB | Yes (via higher tiers) | $49.99 | $499.99 | | 20 TB | Yes (via higher tiers) | $99.99 | $999.99 | | 30 TB | Yes (via higher tiers) | $149.99 | $1,499.99 |
Key takeaway: If you see a price of $2.99/month for a family plan, that is fixed—it won't jump to $9.99 next month. However, promotional offers like "3 months free" or "50% off for 6 months" are temporary, but the base price after the promo reverts to these fixed numbers.
Maximize Your Storage: The Ultimate Guide to Google One Family Plan Costs (2026)
If you find yourself constantly hitting that dreaded "Storage Full" notification, you aren’t alone. In 2026, managing a digital life for an entire household—from 4K videos to endless email attachments—is a challenge. The good news? Google One family plans
offer a fixed, cost-effective way to share massive storage with up to six people (you plus five others) for one single price. Google One Family Plan Costs
Google One offers tiered pricing based on storage needs. Family sharing is included with every paid plan at no additional cost. 100 GB (Basic):
$1.99 per month or $19.99 per year. This plan is suitable for light users. 200 GB (Standard):
$2.99 per month or $29.99 per year. This plan is suitable for small families sharing standard-resolution photos. 2 TB (Premium):
$9.99 per month or $99.99 per year. This plan is suitable for most families. AI Pro (Premium AI):
$19.99 per month. This tier includes 5 TB of storage and advanced Gemini AI features.
For a family of 2 to 6 people, the Google One Family Plan cost fixed at $2.99 (200GB) or $9.99 (2TB) is one of the best values in cloud storage. It eliminates the anxiety of individual 15GB caps (which fill up fast with 4K videos and high-res photos), provides a VPN for Android users, and offers Google's famously reliable infrastructure.
The "fixed" nature is a blessing: no surge pricing, no overage fees, and no surprise bills. The only time you pay more is if you consciously choose a higher tier or let a promotional discount expire.
Bottom Line: Google has effectively fixed the cost of family storage to a utility-like price. For less than a cup of coffee per month (or $10 for a family of 6), you get peace of mind and unlimited (within your tier) photo backups. Sign up directly via Google One, pay annually, and never worry about variable fees again.

Title: The Economics of Togetherness: Analyzing the Fixed Cost Structure of the Google One Family Plan
Introduction
In the contemporary digital landscape, data has evolved from a luxury to a fundamental utility. As our lives become increasingly entrenched in high-resolution photography, cloud-based productivity suites, and streaming services, the demand for scalable storage solutions has surged. For individuals, managing storage limits is a nuisance; for families, it can be a logistical nightmare. Enter Google One, the subscription service that expands cloud storage beyond the standard free tiers. Among its offerings, the Google One Family Plan stands out as a paragon of economic efficiency. The central thesis of this analysis is that the Google One Family Plan represents a superior financial model for consumers specifically because of its fixed cost structure. By offering a predictable, flat-rate pricing model that allows cost sharing without resource splitting, Google has created a "fixed cost" paradigm that maximizes value and minimizes financial friction for the modern household.
The Evolution of Digital Storage Economics
To understand the value of the Google One Family Plan, one must first appreciate the economic shift it represents. Historically, digital storage was a variable cost tied to hardware. If a user ran out of space, they had to purchase a new hard drive or a device with higher capacity. This was a capital expenditure with high upfront costs. The transition to cloud computing changed this dynamic, converting capital expenditure into operational expenditure. Users now pay a monthly subscription for storage.
However, the initial models of cloud storage were individualistic. If a family of four each needed 200GB of storage, they would require four separate subscriptions. This was a linear cost curve: the more people in the family, the higher the total cost. The Google One Family Plan disrupts this linear progression. It introduces a model where the marginal cost of adding a new family member is effectively zero, provided the total storage pool is not exceeded. This shift from variable per-person costs to a single fixed cost for the group is the defining feature of the service’s economic appeal.
Defining the Fixed Cost Model
In economic terms, a "fixed cost" is an expense that does not change with an increase or decrease in the number of goods or services produced or sold. The Google One Family Plan operates squarely within this definition. For a set monthly or annual fee—typically starting at $2.99 per month for the 200GB tier or $4.99 per month for the 2TB tier—the subscriber secures a specific allocation of storage.
This cost remains "fixed" regardless of how many family members are added to the plan (up to a maximum of six total members). Whether the plan manager adds one additional family member or five, the subscription price remains constant. This structure provides a hedge against inflation for the consumer; unlike utilities where usage might drive the bill higher, the Google One bill is static. The predictability of this expense aids in household budgeting, a critical factor for families managing tight financial margins in an era of subscription fatigue.
The Mechanics of Shared Resources vs. Shared Costs
A crucial distinction of the Google One Family Plan is how it manages the resource pool compared to traditional family plans in other sectors. In many mobile carrier family plans, the data or resources are strictly divided. For example, a family might buy 20GB of data, but it is partitioned into 5GB chunks per person. If one person uses 1GB and another needs 6GB, the user needing more is out of luck despite the family’s overall surplus.
Google One flips this script by creating a communal reservoir. The fixed cost grants access to a total pool of storage. If one family member is a professional photographer utilizing 1.8TB of a 2TB plan, and the other five members are casual users needing only a few gigabytes each, the system accommodates this asymmetry perfectly. This flexibility maximizes the utility of the fixed cost. The consumer extracts more
The Fixed Value of the Google One Family Plan In the modern digital landscape, managing storage across multiple personal devices and individual accounts has become a complex and often costly endeavor. Google One offers a streamlined solution through its family sharing feature, which provides a fixed-cost model for a group of up to six people to consolidate their cloud storage needs. By understanding the cost structure and the inherent value of shared benefits, families can effectively maximize their digital resources while maintaining individual privacy. The Economics of Shared Storage
The primary appeal of the Google One family plan lies in its economic efficiency. While every individual Google account includes 15 GB of free storage, this space is quickly exhausted by high-resolution photos, email attachments, and Drive files. Upgrading to a paid plan unlocks the ability to share that total quota with up to five additional family members at no extra cost beyond the base subscription price. Google One For example, a Basic 100 GB
plan—regularly priced around $1.99/month—can be shared among six people (the plan manager plus five others), bringing the effective cost per person down to approximately $0.33/month. This "fixed" pricing model remains the same regardless of whether one or all six slots are filled, incentivizing full group utilization to achieve the best value. Google One Structure of a Family Plan
The Google One family plan operates under a "Plan Manager" who handles the single monthly or annual payment. The distribution of storage follows a specific hierarchy: Google Help Individual First The 2 TB Family Plan at $9
: Each family member uses their own 15 GB of free personal storage before tapping into the shared Google One quota. Shared Pool
: Once the personal 15 GB is filled, any subsequent files count toward the larger shared storage pool (e.g., 200 GB or 2 TB). Privacy Guardrails
: Despite sharing a storage pool, files remain private. Family members cannot access each other's photos, emails, or documents unless they are explicitly shared. Additional Benefits

Yes, the price of your Google One subscription is fixed regardless of how many people you add.
You do not pay "per person." Whether you share your storage with one person or the maximum of five additional family members, your monthly or annual bill remains the exact same. 💰 How the Pricing Works
Google One allows you to create a "Family Group" to share your storage quota.
Base Cost: You pay the standard rate for your chosen plan (e.g., 100GB, 2TB, or AI Premium).
Member Limit: You can add up to 5 family members (6 people total, including the manager).
The "Fixed" Benefit: If you pay $9.99/month for 2TB, it stays $9.99/month whether you use it alone or share it with 5 others. 🛠️ What is Shared (and What Isn't) Sharing a plan does not mean sharing your private files. What is shared:
Storage Space: Everyone pulls from the same total "pot" of GBs.
Member Benefits: Access to dark web monitoring, extra Google Photos editing tools, and premium Google Meet features. Support: All members get access to Google experts. 🛡️ What remains private: Emails: Family members cannot read your Gmail.
Photos: Your Google Photos library is private unless you manually share an album.
Files: Your Google Drive files are invisible to others unless you grant specific permission. ⚠️ Important Considerations
Storage Distribution: You cannot "cap" how much space a specific family member uses. If one person uploads 1.9TB of video, the rest of the family is left with the remaining 100GB.
The Manager Pays: Only the "Family Manager" is billed. You cannot currently split the bill automatically through Google; one person pays the fixed cost, and others would need to reimburse them manually.
Personal 15GB First: Each member uses their own free 15GB of storage first. Once they hit that limit, they automatically start using the shared Google One storage.
💡 Pro Tip: If you want to lower the "fixed" cost even further, switch to annual billing. Most Google One plans offer a discount (usually around 16–17%) if you pay for the full year upfront instead of monthly. If you'd like, I can help you:

The Strategic Value of a Fixed-Cost Google One Family Plan In an era of "subscription fatigue," where monthly fees for streaming, software, and storage seem to climb unpredictably, the concept of a fixed-cost Google One Family Plan
represents more than just a budgeting tool—it is a cornerstone of digital stability
. As households become increasingly dependent on cloud ecosystems for everything from sentimental photos to critical work documents, the ability to lock in a price for shared storage offers a rare form of consumer protection in a volatile market. 1. Economic Predictability for Modern Households
The primary appeal of a fixed-cost model is the elimination of "price creep." Standard subscription models often subject users to sudden hikes as platforms scale or change their terms of service. By contrast, a fixed-rate plan allows family managers to integrate digital costs into their long-term financial planning without fear of mid-year adjustments. This transparency is particularly valuable for large families who utilize the maximum sharing capacity—up to five additional members—where the value proposition hinges on a consistent, predictable per-user cost. 2. Maximizing Shared Utility
A Google One Family Plan is inherently designed for collective efficiency. Unlike individual plans where storage might go to waste, a shared pool—ranging from 100GB to 2TB or more—ensures that the "heavy users" in the family can benefit from the unused space of others. When this cost is fixed, the "price-per-gigabyte" remains a stable metric, allowing families to grow their digital footprint—uploading years of 4K video or high-resolution backups—without the looming threat of an expensive tier jump being forced by a base price increase. 3. Streamlining Digital Legacy and Security
Beyond simple storage, Google One provides premium features like enhanced security tools and Google Photos
editing capabilities. A fixed-cost commitment encourages families to fully commit to the ecosystem. When users know their costs are locked, they are more likely to utilize the Google Family Group features for shared calendars, YouTube Premium (if bundled), and Google Play Family Library
access. This fosters a "digital home" environment where the barriers to entry are low and the financial overhead is static. 4. Conclusion
While the tech industry continues to trend toward flexible, often fluctuating pricing, a fixed-cost Google One Family Plan
serves as a vital anchor for the digital-first family. It transforms cloud storage from a fluctuating utility into a stable, managed asset. By providing price certainty alongside high-capacity sharing, Google empowers families to focus on capturing memories and collaborating on projects, rather than managing the shifting sands of subscription billing.

The dataset consists of 10% of all the events recorded by the Pierre Auger Observatory that pass high-level quality selection checks (explained below). The periods of data recording are: from January 2004 to August 2018 for the SD1500 events; from December 2004 to December 2017 for the hybrid events (SD1500 & FD); from January 2014 to August 2018 for the SD750 events and for the hybrid events involving the HEAT-Coihueco telescopes. These Open Data have been subjected to the reconstruction procedures used by the Auger Collaboration in their official software [Nucl. Instr. Meth. A 580 (2007) 1485–1496 (arXiv)] and explained in [ JCAP 08(2014) 019 (arXiv)], [ JINST 15 (2020) P10021 (arXiv)] and [ Eur. Phys. J. C 81, 966 (2021) (arXiv)].
Pseudo-raw data for the observed cosmic rays are released in JSON format files, one for each event, named "Auger_yydddsssssxx.json", where "yydddsssssxx" is the "id" number which identifies the event. Files consist of different sections, whose number and type depend on the kind of event. Sections and variables are listed below.
In addition, summary files (CSV format) contain the high level information for each reconstructed event in the specific data sample. More details are also given in the semantics section. Note that events observed by multiple FD sites (Eyes) appear once per Eye in the summary file and this has to be taken into account to avoid double counting.
Download the JSON pseudo-raw data for all cosmic ray events (826 MB - individual event JSON data can also be downloaded individually from the event display page).
Download the CSV summary files (8 MB). This file includes all the reconstruction information and should be enough for most physics analyses.
All Auger Open Data have a DOI that you are requested to cite in any applications or publications. The DOI of the main dataset is 10.5281/zenodo.4487612, which always points to the current version. The Auger Collaboration does not endorse any work, scientific or otherwise, produced using these data, even if available on, or linked from, this portal.
The Open Data includes 10% of the data set used in the Auger physics analyses presented at the International Cosmic Ray Conference in 2019. They correspond to the events for which the identification number ("sdid") ends with a zero.
The Open Data recorded with the water-Cherenkov detector arrays are the result of a set of selection criteria applied to detected events. The first requires that the WCD with the highest signal, or closest to the core, is surrounded by a hexagon of six stations that are operational. This requirement ensures adequate sampling of the shower and allows for the evaluation of the aperture of the surface detector in a purely geometrical manner in the energy regime where the array is fully efficient [Nucl.Instrum.Meth.A 613 (2010) 29-39 (arXiv), JCAP 08(2014) 019 (arXiv)], [ Eur. Phys. J. C 81, 966 (2021) (arXiv)]. The detection-efficiency of the SD1500 array is greater than 97% for events with energy above 2.5 x 1018eV arriving from a zenith angle (θ) less than 60°, and 4 x 1018 eV for showers arriving between 60° and 80°. For the SD750 array, the detection efficiency becomes greater than 98% at around 1017eV.
The Open Data of the surface detector arrays have also been subjected to criteria that guarantee good performance of operation: for example, time intervals during which the data acquisition was unstable are excluded; photomultipliers with unstable baseline, loss of calibration data, unstable ratio between high- and low-gain channels, etc., are also excluded.
The Open Data for the hybrid events are selected by requiring the fulfillment of several criteria, including hardware status (at the level of the telescope and pixels) and requiring the quality of the reconstruction of shower geometry and profile (including uncertainties associated with the energy and depth of maximum). Additionally, the atmospheric characterization (including information on the presence of aerosols and clouds, and the vertical optical transparency) is taken into account. Specific fiducial volume cuts are applied for different analyses in order to achieve uniform acceptance and minimize the uncertainties on the corresponding observables. Events passing the selection for the energy spectrum, the calibration, and/or the depth of maximum analyses, are flagged accordingly ("hdSpectrum","hdCalib","hdXmax").
To illustrate the reconstruction procedures used for events recorded with WCD arrays and with the air-fluorescence telescopes (and the related variables) two exemplary events are used. One (event 81847956000) triggered simultaneously the SD1500 array and two FD sites, the other (event 141476578900) triggered the SD750 array and the HEAT-Coihueco telescopes. The figures are extracted from the event-display, where these events are available: event 81847956000, event 141476578900.

In the adjacent figures the ground view of each event is shown. The colored squares indicate the FD sites that observed the shower. The colored dots correspond to SD1500 (SD750) stations which were hit by the shower particles and that have been selected for the reconstruction process ("recstations"). The areas of the dots are proportional to the logarithm of the magnitude of the signal sizes, while the colors represent the time of arrival ("t") at the different stations (green: early stations; red: late stations). The grey dots indicate detectors which have recorded no signal, while the black dots represent those which, even if a signal was recorded, were not part of the shower event ("isSelected=0"), but due to an unassociated cosmic ray (usually a muon). The position of the core ("x", "y", "z"), where the highest signal would be observed, is marked by the head of the blue arrow, which indicates the azimuth angle ("phi") of the shower direction of arrival.
The signal timing and signal sizes measured in each selected station, as well as the positions of the stations (the stations coordinates can be found in sdMap.csv), are the inputs for the reconstruction of the events [JINST 15 (2020) P10021 (arXiv)].
The signal features are computed from the output of the flash analogue-to-digital converters (FADCs) associated with each photomultiplier (PMT). Examples of such signals in two stations in the event are displayed in the figure below.
FADC traces of the PMTs signals in two different WCD stations hit by the shower
The FADC trace, shown for each of the 3 PMTs with different colors, are for a station 565 m away from the core (top figure) and one 2602 m away (bottom figure). They are expressed in terms of VEMs (Vertical Equivalent Muons) where one VEM is the signal due to a single muon traversing a detector. The FADCs are digitised so as to give a measurement every 25 ns. The traces from the closer detector are relatively smooth and are compressed into ~1000 ns while at the greater distance the signal arrives over a period of ~4000 ns. Most of the large spikes seen in the more distant FADC signals are probably due to muons which cross the detector, though high-energy electrons that would penetrate the full depth of the water may be present close to the shower axis and are expected to arrive early in the time window. More typically, however, the mean energy of an electron or photon in a shower at several 100 metres from the shower axis is ~10 MeV in contrast to typical muon energies of > 500 MeV. The energy loss of a relativistic particle that traverses a tank in a vertical direction is ~250 MeV.
The signal timing, in terms of start- and stop-times (located at "signalStartBin", "signalStopBin" in the trace, respectively), is determined from a separate analysis of the structures of the FADC traces, after the subtraction of the baselines, in the high-gain channel of each working PMTs in a station. By merging the extracted information from the PMTs, the start-time ("t") that is determined represents the best estimate of the beginning of the passing shower front. The procedure applied to determine the stop-time ensures that all particles belonging to the shower are included while excluding as many accidental signals as possible. The signal size ("signal") is obtained by integrating the final trace (converted in VEMs), which consists of the bin-by-bin average of the traces of the PMTs in the high-gain channel ("sat=0"), or low-gain channel if the high-gain is saturated ("sat=1", "sat=2"), between the determined start and stop times.
To initiate the reconstruction of the zenith and azimuth angles of the shower arrival direction ("theta", "phi"), an estimation of the location of the core on the ground is obtained as the signal-weighted center-of-mass of the selected stations in an event. Then the start-times of the signals in each station are fitted to a model that describes the shower particles as moving with the speed of light in a curved shower front. Thus the two directional cosines and the time at which the core strikes the ground are determined. The radius of curvature ("R") is also set as a free parameter when five or more stations are selected for the event reconstruction. The arrival direction is determined to a precision of about 1°, a figure that falls as the energy (and hence the multiplicity of stations triggered) rises.
Fall-off of the signals size as a function of the distance to the shower core (blue dots) fitted with the lateral distribution function (yellow line)
The reconstruction of the arrival direction of the shower is followed by the calculation of the energy estimator and of the position of the impact point at the ground ("x", "y", "z"). For vertical events, a fit to a lateral distribution function (ldf) is performed. In the adjacent figure the fall-off of the signal sizes (blue dots) with distance ("spDistance"), in a plane perpendicular to the direction of the shower, is shown together with a yellow line that defines the ldf used to fit the event. The signal at an “optimal distance”, which depends predominantly on the spacing between detectors and can be found accurately independent of knowledge of the exact shape of the ldf, represents the shower size and acts as a surrogate for the energy of the primary particle which has initiated the shower. For a spacing of 1500 m the optimal distance is 1000 m, thus the reference signal is S(1000), ("s1000"), while for a spacing of 750 m the optimal distance is 450 m and the reference signal is is S(450), ("s450"). The uncertainty in the measurement of S(1000) decreases from 15% at a shower size of 10 VEM (roughly corresponding to E ~ 2.5 x 1018 eV) to 5% at the highest shower sizes. The uncertainty on the impact point is of order 50 m. The reference signal is influenced by changes in atmospheric conditions that affect shower development [JINST 12 (2017) P02006 (arXiv)] and by the geomagnetic field that impacts on the shower particle-density [JCAP11 (2011) 022 (arXiv)]. Corrections of order 2% and 1% for the atmospheric and geomagnetic effects ("wcorr", "gcorr"), respectively, are made to the reference signal.
Parameterized densities of muons for a 10 EeV proton shower at zenith angles of 60°, 70° and 80°arriving from azimuth, φ = 0°. Radial units are in kilometers. The coordinate system is defined in the plane perpendicular to the shower direction with the y-axis parallel to the projection of the Earth’s magnetic field on that plane. The magnitude of the muon densities are indicated along the solid line.
For inclined events, the method used for reconstruction of the energy estimator and core position is modified. Due to their long path in the atmosphere, muons, the particles that contribute most of the signal for inclined showers, are deflected in the Earth’s magnetic field. As a result, the near-cylindrical symmetry of the showers is lost and the distribution of the signals at the ground is described with a 2D ldf (so-called muon map). By scaling the muon map of a reference proton shower at 1019 eV an energy estimator, N19 ("n19"), is obtained. The uncertainty in N19 decreases from 13% at E ~ 4 x 1018 eV to 4% at the highest energy. The uncertainty on the impact point is of order 100 m [ JCAP 08(2014) 019 (arXiv)].
For a cosmic ray of a given energy, the shower size estimators depend on the zenith angle because, once it has passed the depth of shower maximum, a shower is attenuated as it traverses the atmosphere. The intensity of cosmic rays, defined as the number of events per steradian above some S(1000)/S(450)/ N19 threshold, is thus dependent on zenith angle. Given the highly isotropic flux, the intensity is expected to be independent from the zenith angle after correction for the attenuation. Based on this principle, an empirical procedure, the so-called Constant Intensity method, is used to determine the attenuation curve as a function of the zenith angle and therefore an energy estimator, independent of the zenith angle. This can be thought as being the signal at 1000 (450) meters, or N19, that a shower would have produced had it arrived at 38° (35°) or 68°, the median angles of the zenith distribution for the SD1500 (SD750) array in the respective angular ranges (vertical or inclined). The energy ("energy") associated with the SD event is derived from a calibration between the energy estimator S38 (S35) or N68, "s38" ("s35") or "n68", and the energy measured by the FD ("totalEnergy") in golden-hybrid events. The SD1500 energy resolution is about 20% at 2x1018 eV and about 7% above 2x1019 eV. The systematic uncertainty on the energy scale is 14% [Physical Review D 102, 062005 (2020) (arXiv)]. The SD750 energy resolution is about 22% at 1017 eV and about 12% above 1018 eV [ Eur. Phys. J. C 81, 966 (2021) (arXiv)].In the adjacent figure the shower images observed with the Los Leones, Coihueco, and HEAT-Coihueco fluorescence telescopes are displayed. The colors show the time at which the light reaches each pixel ("pixelTime"). The trigger conditions require some pixels to be aligned, but background light can also be recorded (the variable "pixelStatus" will also tell up to which level they are used to reconstruct the shower).
Together with the telescope position, the direction that the pixels point to in the sky (shown in Elevation and Azimuth angles -- from fdPixelMap.csv) determine a plane containing the shower development in the atmosphere ("SDP") . The shower axis within this plane is obtained from the time of arrival of the light at the camera ("TimeFit"), summing the contributions of two distances traveled at the speed of light: the distance crossed by the shower front to a point where light is emitted and the distance this light crosses to the telescope. The time at which the shower front reaches the ground, given by the timing information from the WCD station with the highest signal ("hottestStationId"), sets a strong constraint on the hybrid geometrical reconstruction, (providing "theta", "phi", "x", "y", "z"). For this event, the hottest WCD station is found at ("distSdpStation") around 500 m from the shower detector plane defined with Los Leones and around 250 m for the plane defined with Coihueco (at slightly larger distances from the reconstructed shower axis, "distAxisStation").
The next figure shows the energy deposited ("energyDepositProf") in the atmosphere as a function of the slant depth crossed by the cosmic ray ("atmDepthProf"), as seen independently in the two FD sites. LL is shown in blue and CO in green: the density of points and the uncertainty changes with the position from which the shower is seen.
The integral of this curve gives a direct measurement of the calorimetric energy ("calEnergy") of the primary particle, while the depth at which the maximum of the energy deposition occurs ("xmax") is used to infer the primary particle properties. The reconstruction of each point in the profile from the light seen on the camera ("pixelCharge") depends on the distance to the telescope and on the height in the atmosphere at which the energy is deposited ("distXmax" and "heightXmax").
The detected fluorescence light is proportional to the energy deposition and is emitted isotropically. Cherenkov light is emitted in the forward direction and enters the telescope directly when the shower axis is viewed from the telescope at a small angle ("minViewAngle"). It can also be scattered and reach the telescope at later times, which usually accounts for a fraction of the total detected photons ("cherenkovFraction"). For this example, the minimum viewing angles are 18° and 52°, at LL and CO, respectively; with corresponding Cherenkov fractions of 17% and 7%. Both Fluorescence and Cherenkov light are used in the reconstruction [Nucl.Instrum.Meth.A 798 (2015) 172-213 (arXiv)]. The light is attenuated and scattered when crossing the atmosphere, so both the distance traveled and the atmospheric parameters must be taken into account when estimating the expected number of detected photons that correspond to the emission at each position in the shower development, which is proportional to the deposited energy. The energy deposited per unit depth (dE/dX) in the atmosphere increases, at first, with the multiplication of particles in the shower, and then decreases as the energy loss by ionisation starts to exceed that by Bremsstrahlung. This behavior gives rise to a reasonably universal profile shape, where the position of the maximum Xmax depends on the primary particle type (and its energy). The shape of the profile is described by xmax and the corresponding dEdXmax and two other variables (upsL and uspR) [JCAP 03 (2019) 018 (arXiv)]. The integration of the profile provides a direct calorimetric measurement of the total energy of the primary cosmic ray (calEnergy), pending the correction from the energy taken away by muons (that can be partially detected in the SD) and neutrinos (which will go undetected) [Phys. Rev. D 100, 082003 (2019) (arXiv)] to finally obtain the totalEnergy.
The 2 TB Family Plan at $9.99/month ($119.88/year)
The price is fixed for your current plan. But if you run out of space and upgrade (e.g., from 200GB to 2TB), the new fixed price applies immediately, prorated for the remainder of your billing cycle. Google does not penalize you for upgrading, but you cannot downgrade mid-cycle.
If you are currently on a Google One Family Plan and want to confirm your locked-in price, follow these steps:
Red flags to watch for:
Google offers three primary tiers that support family sharing. Note: The basic 100GB plan does exist, but it does not support family sharing. To get the "Family Plan" features, you must start at the 200GB tier or higher.
| Storage Tier | Family Sharing Supported? | Monthly Fixed Cost | Annual Fixed Cost (Save ~16%) | | :--- | :--- | :--- | :--- | | 100 GB | No (Individual only) | $1.99 | $19.99 | | 200 GB | Yes | $2.99 | $29.99 | | 2 TB | Yes | $9.99 | $99.99 | | 5 TB | Yes | $24.99 | $249.99 | | 10 TB | Yes (via higher tiers) | $49.99 | $499.99 | | 20 TB | Yes (via higher tiers) | $99.99 | $999.99 | | 30 TB | Yes (via higher tiers) | $149.99 | $1,499.99 |
Key takeaway: If you see a price of $2.99/month for a family plan, that is fixed—it won't jump to $9.99 next month. However, promotional offers like "3 months free" or "50% off for 6 months" are temporary, but the base price after the promo reverts to these fixed numbers.

Title: The Economics of Togetherness: Analyzing the Fixed Cost Structure of the Google One Family Plan
Introduction
In the contemporary digital landscape, data has evolved from a luxury to a fundamental utility. As our lives become increasingly entrenched in high-resolution photography, cloud-based productivity suites, and streaming services, the demand for scalable storage solutions has surged. For individuals, managing storage limits is a nuisance; for families, it can be a logistical nightmare. Enter Google One, the subscription service that expands cloud storage beyond the standard free tiers. Among its offerings, the Google One Family Plan stands out as a paragon of economic efficiency. The central thesis of this analysis is that the Google One Family Plan represents a superior financial model for consumers specifically because of its fixed cost structure. By offering a predictable, flat-rate pricing model that allows cost sharing without resource splitting, Google has created a "fixed cost" paradigm that maximizes value and minimizes financial friction for the modern household.
The Evolution of Digital Storage Economics
To understand the value of the Google One Family Plan, one must first appreciate the economic shift it represents. Historically, digital storage was a variable cost tied to hardware. If a user ran out of space, they had to purchase a new hard drive or a device with higher capacity. This was a capital expenditure with high upfront costs. The transition to cloud computing changed this dynamic, converting capital expenditure into operational expenditure. Users now pay a monthly subscription for storage.
However, the initial models of cloud storage were individualistic. If a family of four each needed 200GB of storage, they would require four separate subscriptions. This was a linear cost curve: the more people in the family, the higher the total cost. The Google One Family Plan disrupts this linear progression. It introduces a model where the marginal cost of adding a new family member is effectively zero, provided the total storage pool is not exceeded. This shift from variable per-person costs to a single fixed cost for the group is the defining feature of the service’s economic appeal.
Defining the Fixed Cost Model
In economic terms, a "fixed cost" is an expense that does not change with an increase or decrease in the number of goods or services produced or sold. The Google One Family Plan operates squarely within this definition. For a set monthly or annual fee—typically starting at $2.99 per month for the 200GB tier or $4.99 per month for the 2TB tier—the subscriber secures a specific allocation of storage.
This cost remains "fixed" regardless of how many family members are added to the plan (up to a maximum of six total members). Whether the plan manager adds one additional family member or five, the subscription price remains constant. This structure provides a hedge against inflation for the consumer; unlike utilities where usage might drive the bill higher, the Google One bill is static. The predictability of this expense aids in household budgeting, a critical factor for families managing tight financial margins in an era of subscription fatigue.
The Mechanics of Shared Resources vs. Shared Costs
A crucial distinction of the Google One Family Plan is how it manages the resource pool compared to traditional family plans in other sectors. In many mobile carrier family plans, the data or resources are strictly divided. For example, a family might buy 20GB of data, but it is partitioned into 5GB chunks per person. If one person uses 1GB and another needs 6GB, the user needing more is out of luck despite the family’s overall surplus.
Google One flips this script by creating a communal reservoir. The fixed cost grants access to a total pool of storage. If one family member is a professional photographer utilizing 1.8TB of a 2TB plan, and the other five members are casual users needing only a few gigabytes each, the system accommodates this asymmetry perfectly. This flexibility maximizes the utility of the fixed cost. The consumer extracts more
The Fixed Value of the Google One Family Plan In the modern digital landscape, managing storage across multiple personal devices and individual accounts has become a complex and often costly endeavor. Google One offers a streamlined solution through its family sharing feature, which provides a fixed-cost model for a group of up to six people to consolidate their cloud storage needs. By understanding the cost structure and the inherent value of shared benefits, families can effectively maximize their digital resources while maintaining individual privacy. The Economics of Shared Storage
The primary appeal of the Google One family plan lies in its economic efficiency. While every individual Google account includes 15 GB of free storage, this space is quickly exhausted by high-resolution photos, email attachments, and Drive files. Upgrading to a paid plan unlocks the ability to share that total quota with up to five additional family members at no extra cost beyond the base subscription price. Google One For example, a Basic 100 GB
plan—regularly priced around $1.99/month—can be shared among six people (the plan manager plus five others), bringing the effective cost per person down to approximately $0.33/month. This "fixed" pricing model remains the same regardless of whether one or all six slots are filled, incentivizing full group utilization to achieve the best value. Google One Structure of a Family Plan
The Google One family plan operates under a "Plan Manager" who handles the single monthly or annual payment. The distribution of storage follows a specific hierarchy: Google Help Individual First
: Each family member uses their own 15 GB of free personal storage before tapping into the shared Google One quota. Shared Pool
: Once the personal 15 GB is filled, any subsequent files count toward the larger shared storage pool (e.g., 200 GB or 2 TB). Privacy Guardrails
: Despite sharing a storage pool, files remain private. Family members cannot access each other's photos, emails, or documents unless they are explicitly shared. Additional Benefits
The fixed cost of a Google One subscription includes more than just storage. Depending on the plan, members might also receive: Plans & Pricing to Upgrade Your Cloud Storage - Google One
Yes, the price of your Google One subscription is fixed regardless of how many people you add.
You do not pay "per person." Whether you share your storage with one person or the maximum of five additional family members, your monthly or annual bill remains the exact same. 💰 How the Pricing Works
Google One allows you to create a "Family Group" to share your storage quota.
Base Cost: You pay the standard rate for your chosen plan (e.g., 100GB, 2TB, or AI Premium).
Member Limit: You can add up to 5 family members (6 people total, including the manager).
The "Fixed" Benefit: If you pay $9.99/month for 2TB, it stays $9.99/month whether you use it alone or share it with 5 others. 🛠️ What is Shared (and What Isn't) Sharing a plan does not mean sharing your private files. What is shared:
Storage Space: Everyone pulls from the same total "pot" of GBs.
Member Benefits: Access to dark web monitoring, extra Google Photos editing tools, and premium Google Meet features. Support: All members get access to Google experts. 🛡️ What remains private: Emails: Family members cannot read your Gmail.
Photos: Your Google Photos library is private unless you manually share an album.
Files: Your Google Drive files are invisible to others unless you grant specific permission. ⚠️ Important Considerations
Storage Distribution: You cannot "cap" how much space a specific family member uses. If one person uploads 1.9TB of video, the rest of the family is left with the remaining 100GB.
The Manager Pays: Only the "Family Manager" is billed. You cannot currently split the bill automatically through Google; one person pays the fixed cost, and others would need to reimburse them manually.
Personal 15GB First: Each member uses their own free 15GB of storage first. Once they hit that limit, they automatically start using the shared Google One storage.
💡 Pro Tip: If you want to lower the "fixed" cost even further, switch to annual billing. Most Google One plans offer a discount (usually around 16–17%) if you pay for the full year upfront instead of monthly. If you'd like, I can help you:

The Strategic Value of a Fixed-Cost Google One Family Plan In an era of "subscription fatigue," where monthly fees for streaming, software, and storage seem to climb unpredictably, the concept of a fixed-cost Google One Family Plan
represents more than just a budgeting tool—it is a cornerstone of digital stability
. As households become increasingly dependent on cloud ecosystems for everything from sentimental photos to critical work documents, the ability to lock in a price for shared storage offers a rare form of consumer protection in a volatile market. 1. Economic Predictability for Modern Households
The primary appeal of a fixed-cost model is the elimination of "price creep." Standard subscription models often subject users to sudden hikes as platforms scale or change their terms of service. By contrast, a fixed-rate plan allows family managers to integrate digital costs into their long-term financial planning without fear of mid-year adjustments. This transparency is particularly valuable for large families who utilize the maximum sharing capacity—up to five additional members—where the value proposition hinges on a consistent, predictable per-user cost. 2. Maximizing Shared Utility
A Google One Family Plan is inherently designed for collective efficiency. Unlike individual plans where storage might go to waste, a shared pool—ranging from 100GB to 2TB or more—ensures that the "heavy users" in the family can benefit from the unused space of others. When this cost is fixed, the "price-per-gigabyte" remains a stable metric, allowing families to grow their digital footprint—uploading years of 4K video or high-resolution backups—without the looming threat of an expensive tier jump being forced by a base price increase. 3. Streamlining Digital Legacy and Security
Beyond simple storage, Google One provides premium features like enhanced security tools and Google Photos
editing capabilities. A fixed-cost commitment encourages families to fully commit to the ecosystem. When users know their costs are locked, they are more likely to utilize the Google Family Group features for shared calendars, YouTube Premium (if bundled), and Google Play Family Library
access. This fosters a "digital home" environment where the barriers to entry are low and the financial overhead is static. 4. Conclusion
While the tech industry continues to trend toward flexible, often fluctuating pricing, a fixed-cost Google One Family Plan
serves as a vital anchor for the digital-first family. It transforms cloud storage from a fluctuating utility into a stable, managed asset. By providing price certainty alongside high-capacity sharing, Google empowers families to focus on capturing memories and collaborating on projects, rather than managing the shifting sands of subscription billing.

In addition to data, auxiliary data are available here, namely the list of the positions of the SD detectors and of the FD pixels, as well as the SD exposure and the FD acceptance.
The "sdMap.csv" file contains the position in UTC coordinate system of all stations of the surface detector and time period of activity, in the following format:
The "fdPixelMap.csv" file contains information about the position of a pixel in the FD telescopes and its pointing direction:
The exposure files ("sd1500exposure.csv", "sd1500exposureInclined.csv" and "sd750exposure.csv") contain, for each SD event, the value of the exposure cumulated up to the time of its detection. Above the full efficiency threshold, (2.5 EeV for SD1500 vertical events, 4 EeV for the inclined ones, and 0.1 EeV for SD750 events) the calculation of the exposure is purely geometrical, obtained from the integration of the geometrical aperture over the observation time:
The FD-related "fdXmaxAcceptance.csv" and "fdXmaxResolution.csv" files are CSV versions of the Tables Appendix B.II and Appendix B.III as published in [Phys. Rev. D 90, 122005 (2014) (arXiv)] Appendix A. In these tables energy-dependent properties of the acceptance and resolution of FD-reconstructed Xmax are tabulated:
