Quasar properties from SDSS. III. SDSS-IV.

DOI

This paper provides the compilations of properties of the quasars newly obtained by the Sloan Digital Sky Survey (SDSS) during the fourth stage (SDSS-IV). The catalog is available on the journal's website. We have measured the main properties of emission lines around CIV, MgII, H{beta}, and H{alpha} spectral regions. We estimate the quasar redshifts from our fits of narrow [OIII], broad MgII, and broad CIV emission lines and find that the best redshifts included in DR16Q are robust with respect to our measurements. Based on the broad CIV, MgII, H{beta}, and/or H{alpha} emission lines, we calculate the virial black hole mass with empirical relationships provided by previous works. Systematic biases are found among the different line-based mass estimators.
