DESI PROVABGS posterior products — L1 (release v1)
This L1 repository contains 222,747 galaxies matched across the release in one shard (about 1.3 GB).
Schema
The dataset includes PROVABGS_MCMC (about 100×13 posterior samples per galaxy, retained in full), PROVABGS_THETA_BF (the best fit), derived properties such as LOG_MSTAR, Z_MW, TAGE_MW, and AVG_SFR, selection and quality columns, and object_id (TARGETID).
kshitijd/mmu-l2-provabgs provides an L2 table of 16th, 50th, and 84th posterior percentiles for each parameter. The full samples remain in L1.
Leakage warning
These posteriors were inferred from the DESI spectra and Legacy photometry included in this release. A model that predicts PROVABGS quantities from those inputs reproduces part of the PROVABGS inference pipeline. Describe this dependency clearly in benchmarks because it creates target leakage.
