Abstract
We have modeled the peculiar bidimensional shape of the emission lines in a sample of four disk galaxies as due to the motion of a gaseous disk rotating in the combined potential of a central point-like mass and of a diffuse stellar disk. From the values we derive for the central masses and the luminosities of the corresponding bulges we obtain a median M_BH/L_bulge~0.16 (in solar units). This value is one order of magnitude larger than the median value derived by Ho (1998) but still within the scatter.
