Notes. Best-fit parameters of the smTF relation, expressed as log M = a (log V2.2−log V2.2,0) + b, where log V2.2,0 = 2.0dex is the “pivot” value adopted to minimize the correlation between the errors on a and b. The forward parameters are obtained by inverting the best-fit parameters from the inverse fit. The slope of the relation is a and b is the y-intercept. σintr, rms and δmed are the intrinsic scatter, the total scatter and the median error, respectively, for both the velocity and stellar mass in logaritmic units. ;
