Abstract:
We compile black hole (BH) masses for ∼60000 quasars in the redshift
range 0.1~<z~<4.5 included in the Fifth Data Release of the Sloan
Digital Sky Survey (Schneider et al. 2007, Cat. VII/252), using virial
BH mass estimators based on the Hβ, MgII, and CIV emission lines.

Note (1): Using TARGET photometry, corrected for Galactic extinction using
the Schlegel, Finkbeiner & Davis (1998ApJ...500..525S 1998ApJ...500..525S) map. If TARGET
value is unavailable in the database, using BEST photometry instead
(101 objects).
