VizieR Online Data Catalog: SDSS-IV/SPIDERS X-ray PS Spectroscopic Catalog (Comparat+, 2020)

SPIDERS (SPectroscopic IDentification of ERosita Sources) is a SDSS-IV program aimed at obtaining spectroscopic classification and redshift measurements for complete samples of sufficiently bright X-ray sources. We describe the SPIDERS X-ray Point Source Spectroscopic Catalogue, which contains 11092 observed spectra drawn from a parent sample of 14759 ROSAT and XMM sources over an area of 5129deg² covered in SDSS-IV by the eBOSS survey. This program represents the largest systematic spectroscopic observation of an X-ray selected sample. A total of 10970 (98.9%) of the observed objects are classified, and 10849 (97.8%) have secure redshifts. The majority of the spectra, 10070 are AGN, 522 are cluster galaxies, and 294 are stars.

SDSS-IV/BOSS spectrographs observations between 2014 and 2019.
