Compilation of all 28 derived rotation curves with different scalings for each panel. The sample of rotation curves is divided in two according to central disk surface brightness: gray curves correspond to galaxies of lower surface brightness ( mag/arcsec²) and black curves correspond to galaxies of higher surface brightness ( mag/arcsec²). In the upper left panel, no scaling is applied to the rotation curves. In the bottom right panel, the rotation curves are scaled both in radius and amplitude.
