The Gaia-unWISE Quaia quasar catalog cut at G < 20.0, with its nside-64 selection function map. Powers the ISW cross-correlation detection, the isotropy/lattice null batteries, and the registry's model self-kill: the raw 9.9-sigma quasar dipole that dissolved into the kinematic expectation under adversarial cuts.

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.
