Stellar Tully-Fisher relation (top panels) and Fall relation (bottom panels) for SPARC galaxies with M_⋆ determined using the dynamical method (first column), the photometric method (second column), the MSC method (third column), and Equation (1) with Υ_disc = 0.5 (fourth column). Only galaxies for which all four M_⋆ estimates are available are shown. Galaxies with p(> χ²) above and below 0.05 are shown with filled and open circles, respectively. In each panel, the dashed black line shows the best linear fit to the filled circles, with the yellow band representing the vertical observed scatter (σ_M⋆ or σ_j⋆). The best-fit parameters are reported in Table 1 and on the top left portion of each panel.
