In order to aid in sitcom activities we would like to add ATLAS-REFCAT2 (https://archive.stsci.edu/prepds/atlas-refcat2/index.html) to /datasets/refcats and ingest into /repo/main.
This refcat will be used to calibrate AuxTel imaging surveys particularly in regions the PS1 reference catalog does not cover and for bright stars. Also, ATLAS-REFCAT2 is more appropriate for initial photometric calibration than Gaia because the bandpasses are more similar to the ones used for Rubin.

ATLAS-REFCAT2 is an all-sky reference catalog containing nearly one billion stars down to apparent magnitude m ~19. The catalog includes PanSTARRS DR1, ATLAS Pathfinder, ATLAS re-flattened APASS, SkyMapper DR1, APASS DR9, Tycho-2, and the Yale Bright Star Catalog. Gaia DR2 serves as the source of the astrometric solution for ATLAS-REFCAT2. The ATLAS Pathfinder telescope was used to collect g,r,i photometry for stars brighter than the 14th magnitude bright limit of PanSTARRS, and to extend the reference system below -30 declination. For more information see http://dx.doi.org/10.17909/t9-2p3r-7651.

The full catalog will take up ~200 GB of disk space.
