SPARC rotation curves + mass models
The 175-galaxy SPARC sample: MassModels_Lelli2016c.mrt is the file rar_a0_zero_param_test.py actually reads to build the radial-acceleration relation and test the parameter-free MOND scale a0 = cH0/6 (USR-2026-0049, provisional/marginal at +2.6 sigma_median canonical, +0.3 sigma free-fit). NOTE the claim's own limitation, restated here because it is the dominant uncertainty: the stellar mass-to-light ratio Upsilon_disk swings the offset by 4.30 sigma_median across its accepted band, which swamps the signal. This data cannot settle the question without a Upsilon_disk prior it does not contain.

Used by claims
No claim in the registry cites this dataset yet. It's catalogued anyway — unused data still gets hashed, and the day a claim leans on it, the provenance is already here.

Serving, honestly
Downloads are served directly from this server today; an object-storage mirror (Tigris) is planned and flips on via config. The upstream archive is always the canonical copy — cite it, not us. Anything we serve must match its published hash.
