Stellar and baryonic Tully-Fisher relationships taken from McGaugh & Schombert (2015). The different lines indicate different samples and wavelengths used in their work. The position of Malin 1 for the ~220 km s^-1 reported in Lelli et al. (2010) is indicated, as well as the “velocity” derived from our model fit (filled circle, open triangle, and open square for respectively the fit based on the photomeric profiles, the gas profile, and both).
