A value-added catalog for SDSS DR16 quasars at z<0.7

The CF is converted from a ratio of infrared (IR) luminosity contributed from AGN dust torus (L_IR_^torus^) and AGN bolometric luminosity (L_bol_), by assuming a nonlinear relation between luminosity ratio and intrinsic CF. We select 37181 type 1 quasars at z<0.7 from the Sloan Digital Sky Survey Data Release 16 quasar catalog.

Their L_bol_, black hole mass (M_BH_), and Eddington ratio ({lambda}_Edd_) are derived by spectral fitting with QSFit. We conduct spectral energy distribution decomposition by using X-CIGALE with a clumpy torus and polar dust model to estimate L_IR_^torus^ without being affected by the contribution of stellar and AGN polar dust to IR emission. For 5752 quasars whose physical quantities are securely determined, we perform a correlation analysis on CF and (i) L_bol_, (ii) M_BH_, and (iii) {lambda}_Edd_.
