Distribution of E(B − V) for the discovered quasars in this work and the literature sample determined by fitting the composite quasars spectrum of Selsing et al. (2016) together with the SMC extinction law (Pei 1992). The radio-loud quasars from the literature sample are stacked on top of quasars from this work. We do not find a significant deviation between the E(B − V) distribution of the RL and RQ quasar sample. For comparison we also plot the E(B − V) Gaussian distribution found by Glikman et al. (2022) of SDSS QSOs at 0.1 <  z ≲ 3 using a similar template fitting method.
