Interactive marimo notebooks running in your browser. Each opens as an app showing figures and controls. The figures are on screen at once; the Python runtime boots in the background, so the controls respond after about half a minute (longer on a phone or tablet).
The code is available four ways: Show code in the ⋯ menu reveals it in
place, edit in browser opens the notebook in a full editor, the download
buttons at the end of each notebook give the marimo (.py) and Jupyter
(.ipynb) files, and the sources are in
examples/,
which you can also run locally.

Paper Figures
The GSF 2026 paper figures the model draws on its own — Figs. 1, 2, 3, 5, 6, 8–12 and SM S1, S2, S3, S4, S7, S8, S9, S14 — ported from the code that produces them, at the paper's figure sizes, weightings, axis ranges, palette and fonts. The measurements are deliberately left out.
-
Cosmic Ray Flux
Differential fluxes for the four GSF mass groups with 1-sigma error bands propagated from the parameter covariance, plus pseudo-experiment draws for nonlinear error propagation.
-
Nucleon Flux
Proton and neutron fluxes per energy-per-nucleon — the input for atmospheric shower and lepton-flux calculations.
-
Solar Modulation
Time-dependent solar modulation of the low-energy flux; local interstellar spectrum vs. modulated periods.
-
Rigidity Cutoff
Geomagnetic rigidity cutoff effects on the flux at Earth.
-
Model Comparison 2017 vs 2025
What changed between the published GSF versions.
-
Reduced Model
Build the pivot-component reduction, validate its coverage against the full covariance, and export it for a downstream fit.
