This page provides supplementary material of quasar properties presented in Rakshit et al. (2020). We present measurements of the spectral properties for a total of about 500,000 quasars 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 Hα, Hβ, Hγ, Mg ii, C iii], C iv and Lyα. From the derived emission line parameters, we estimated single-epoch virial black hole masses (MBH) for the sample using Hβ, Mg ii and C iv emission lines. The sample covers a wide range in bolometric luminosity (logLbol; erg s−1) between 44.4 and 47.3 and logMBH between 7.1 and 9.9 M⊙.
Here, you will find the entire spectral catalog in FITS format and quick assessment spectral fitting plot of each DR14 quasars.
If you any difficulties in using this catalog or you have any suggestions, please let me know.
