The distribution of SMBH masses for both normal (white) and AGN (colored) host galaxies as a function of morphology (Δ [log ₁₀M_• ]  = 0.05 bin). The data of the galaxies have been extracted from the Sloan Digital Sky Survey in redshift interval 0.02 < z < 0.05. The masses have been inferred via the M_• − σ relation using the slope and the normalization taken from Table 2. In order to compare our results with that of Schawinski et al. (2010), we plotted only objects where the measured velocity dispersion is greater than 40 km s^-1.
