VizieR Online Data Catalog: QSO properties from SDSS-DR7 (Shen+, 2011)

We present a compilation of properties of the 105783 quasars in the Sloan Digital Sky Survey Data Release 7 (DR7) quasar catalog (Cat. VII/260). In this product, we compile continuum and emission line measurements around the Hα, Hβ, MgII, and CIV regions, as well as other quantities such as radio properties, and flags indicating broad absorption line quasars, disk emitters, etc. We also compile virial black hole mass estimates based on various calibrations. For the fiducial virial mass estimates we use the Vestergaard & Peterson (VP06; 2006ApJ...641..689V) calibrations for Hβ and CIV, and our own calibration for MgII which matches the VP06 Hβ masses on average. We describe the construction of this catalog and discuss its limitations.
