L _[OIII] /M_BH vs. stellar masses for (left) early- and (right) late-type galaxies. Solid line is the median curve of each sample. Seyfert, LINERs, and composite galaxies are denoted by red, pink, and green colored symbols. Dashed lines from top to bottom indicate the constant L_bol/L_edd = 1, 0.1, and 0.01 by assuming a bolometric correction 3500 for L _[OIII]  (Heckman et al. 2004). The BCGs, marked as crosses, are not used in calculating median values. L _[OIII]  and M_star are computed with H₀ = 70 km s^-1 Mpc^-1.
