Union3 compressed distance moduli from the UNITY1.5 Bayesian framework: 22 spline-node bins with covariance and inverse covariance, plus the original release FITS (mu_mat_union3_cosmo=2_mu.fits) whose first row/column carry z and mu. Third SN sample in the robustness ladder — pushes the evolving-DE preference to 3.3 sigma.

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.
