Table 3: Parameters of the decomposition. The table lists the $\chi ^2$ values of the four different fitting methods (Col. 2), the bulge M/L (Col. 3), the disk M/L (Col. 4), the halo mass (Col. 5), the halo scale length (Col. 6), the maximum circular velocity of the disk component expressed as a percentage of the maximum disk circular velocity (Col. 7), and the X parameter of the respective disk component (Col. 8). The scale lengths of bulge and disk are given by the decomposition of the surface brightness profile as $0\hbox{$.\!\!^{\prime\prime}$ }90$ and $3\hbox{$.\!\!^{\prime\prime}$ }08$, respectively. The meaning of the X parameter is explained in the text (Sect. 4.2).
