The first and second Data Releases of the SkyMapper catalog from The Australian National University's Research School of Astronomy and Astrophysics are stored in Data Lab as astrometric and photometric reference datasets. They have been crossmatched against five other Data Lab datasets: allwise.source, gaia_edr3.gaia_source, nsc_dr2.object, sdss_dr16.specobj, and unwise_dr1.object.
