A list of galaxies with available measurements of stellar disk velocity dispersion and their observed and calculated properties is given in Table 1. For galaxies with line-of-sight velocity exceeding 800 km/s the adopted distances correspond to the Hubble constant $H_0=75$ km/s/Mpc, (except Virgo cluster galaxies for which we took $D=17 $ Mpc). For several nearby galaxies with lower line-of-sight velocity (NGC 3198, NGC 6503, IC750) we used the distance modulus given in Hyperleda database. The disk inclination $i$, color indices corrected for galactic extinction, inclination and redshift, and line-of-sight velocities were also taken from this database. For the cases when the inclinations taken from Hyperleda differed significantly from those given in the original sources referred in the Table, the preference was given to the later ones.

After the estimation of surface density at $R=2h$, it is easy to find a total disk mass: $$\label{Eq-Mdisk}
M_d = 2\pi h^2\, \sigma(2h)\, e^2 \,.$$ In this work a disk photometric radial scalelenght and the scalelenght of surface density are assumed to be equal. In some cases this can be quite rough approximation, but the introduced uncertainty is not so high in comparison with other error sources: a change of $h$ by
