Logarithmic M_BH and bolometric luminosity. Left: for all available lensed quasars (Greene et al. 2010; Sluse et al. 2012; Assef et al. 2011; Peng et al. 2006; Melo et al. 2021) and for non-lensed quasars from Shen et al. (2011, 2019). The open triangles are the M_BH estimates using Hα emission line, filled circles Hβ, open diamonds MgII, and open circles CIV. The measurements from this study are in color. Right: for just the Hα and Hβ emission lines. The red and blue points are our estimates. The dashed lines correspond to Eddington ratios of λ = 1, 0.1, and 0.01.
