Left panel: M_BH obtained from the SE method using the Hβ line plotted vs. the values derived with the X-ray scaling method, with color-coded symbols indicating the redshift of the sources. Middle panel: Same as the left panel with color-coded symbols illustrating the intrinsic absorption N_H in units of 10²² cm⁻². Right panel: Same as the left panel with color-coded symbols describing the level of accretion rate, as defined by log(λ_Edd). Circles indicate M_BH based on the Hβ line, squares are values based on the Mg II line, whereas the two triangles indicate the values based on the C IV line; the diamonds represent the sources whose M_BH values were flagged as unreliable in Rakshit et al. (2020).
