M_BH − σ_[S II] relation for radio-loud quasars (upper panel), FSRQs, SSRQs, and unclassified radio loud quasars are represented by red, blue, and black symbols, respectively. M_BH–σ_[O III] relation of radio-loud quasars (lower panel). In both panels, black, red, and blue solid lines represent the M_BH − σ relations for quiescent galaxies by Kormendy & Ho (2013), Tremaine et al. (2002), and McConnell & Ma (2013), respectively. For [O III], the core of the line is used after decomposing the asymmetric blue wings.
