Sloan Digital Sky Survey (SDSS)
The Data Lab hosts a subset of tables, in particular tables containing spectroscopic measurements, from SDSS DR12, DR13, DR14, DR16, and DR17.
The sdss_dr17.specobj table has been crossmatched with all other datasets in Data Lab within a 1.5 arcsec radius, nearest neighbor only. These tables will appear with x1p5 in their name in our table browser. Example: sdss_dr17.x1p5__specobj__gaia_dr3__gaia_source.
