GD-1 stellar stream track + members
Stellar-stream data for the GD-1 density-gap search (USR-2026-0048), which returned a NULL: global p = 0.587 across 39 bins and 5,000 simulations — no statistically significant gap, so no dark-matter subhalo impact is detected in this stream by this method. gd1_streammapper.ecsv is the file _gd1_gap_test.py reads; the two track files are the published centreline fits. A null published as a first-class result.

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.
