Abstract
We present measurements of the spectral properties for a total of 526,265 quasars, out of which 63% have a continuum signal-to-noise ratio > 3 pixel(-1), selected from the fourteenth data release of the Sloan Digital Sky Survey (SDSS-DR14) quasar catalog. We performed a careful and homogeneous analysis of the SDSS spectra of these sources to estimate the continuum and line properties of several emission lines such as H alpha, H beta, H gamma, Mgii, Ciii], Civ, and Ly alpha. From the derived emission line parameters, we estimated single-epoch virial black hole masses (M-BH) for the sample using H beta, Mgii, and Civemission lines. The sample covers a wide range in bolometric luminosity (
