Fig. 2.


Rotation curves of our sample galaxies as derived using the HI data from the THINGS survey by de Blok et al. (2008). The rotation curves were fitted using a Brandt profile (Eq. (8)) for parametrisation. In each panel, the black circles with error bars represent the rotation curve, whereas the red solid line represents the Brandt profile fit. The best-fit parameters can be found in Table 2.
