M_BH vs. Eddington Ratios for Mejia-Restrepo et al. (2016, black points), Ho et al. (2012, green points) and this work (red points) sources. For the Eddington Ratios, we follow McLure & Dunlop (2004) for the bolometric luminosity and use L_Edd = 1.26 × 10³⁸ (M_BH/M_⊙) erg s^-1 for the Eddington luminosity. We use the Hα-based M_BH, because this is the only Balmer line available for all the samples. The values for our objects are listed in Table 5.
