Mean and median stellar contribution to the circular velocities curves (solid and dashed lines, respectively) inferred from the individual radial force profiles resized in physical units (left) and normalized to the disk scalelength (right), with the subsamples defined based on the total stellar mass (upper panels) and revised Hubble type (lower panels). The 100% and 75% sample coverage in the radial direction are indicated with different line styles. For the upper left panel, the black solid lines correspond to the chi-square minimization fit with a double-component Polyex function (see text), with the resulting parameters listed in Table 4. The vertical error bars, centred in the mean profile, indicate the standard deviation of the mean. In the upper left panel, for the bin with largest M_∗ we also show the sample dispersion with dotted lines.
