Globular-cluster velocities in UDGs, dSph member-star velocities, and Local Group dwarf tables. NO CLAIM IS ATTACHED TO THIS DATASET. It is published as a library — ingested from public sources for work that is not finished, or not started. Its presence here is not evidence of an unpublished result, and nothing in the registry rests on it. Papers and arXiv source bundles that came with the download are deliberately NOT included: those are other authors' copyrighted work.

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.
