TFR with and without applying the mass selection criterion (vi) on galaxies from the TFR sample. The data points and best-fit lines are similar to Fig. 13. The first row shows the TFR using the velocity derived from the best-fit mass models, and the second row the TFR using the flat model. As an indication, we also show as semi-transparent symbols galaxies removed by the mass cut in the rightmost panels. The typical uncertainty on stellar mass and velocity is shown on each panel as a grey error bar.
