DESI Legacy Imaging Surveys
The DESI Legacy Surveys team has produced an inference model and souce catalogs for ~31,000 square degrees of the extragalactic sky in optical and infrared bands. The original Legacy Surveys (MzLS, DECaLS and BASS) conducted dedicated observations of ~14,000 square degrees in three optical bands (\(g,r,z\)) , which has been augmented with additional public DECam data (in \(g,r,i,z\)) and four infrared bands from NEOWISE.
