SDSS Galaxies (SDSS galaxies as imaged by DESI)
Introduced by Smith et al. in Realistic galaxy image simulation via score-based generative models
This is a dataset of 306,006 galaxies whose coordinates are taken from the Sloan Digital Sky Survey Data Release 7 and a modified catalogue from Brinchmann+2003 and Wilman+2010. This volume complete sample has an r-band absolute magnitude limit of $M_r\leq-20$ and a redshift limit of $z\leq0.08$. See Arora+2019 for details.
This catalogue covers a wide range of environments from clusters to groups and field systems. The galaxy images are taken from the Dark Energy Spectroscopic Instrument, and contain $g$, $r$, and $z$ bands.
