DESI BGS Data Release 1 Galaxy Group Catalog

This is a catalog of 2,229,741 galaxies from the Dark Energy Spectroscopic Instrument (DESI) Bright Galaxy Survey (BGS) Data Release 1 (DR1). The galaxies are location in ~2680 deg² of sky with 3-pass coverage and r-band magnitudes <19.5. The catalog provides dark matter halo mass estimates and central/satellite classifications for galaxies in the flux-limited sample. This catalog is DESI DR1 Value Added Catalog.

Sloan Digital Sky Survey Catalogs

For related galaxy group catalogs built using the Self Calibrated Group Finder on the Sloan Digital Sky Survey (SDSS), see the following publications and associated data products. The SDSS catalog uses a slightly different parameterization that allows more realistic scatter especially at lower halo masses where there are few obseved satellites.
