Top-left panel: acceleration curves of galaxies from SPARC in g2 space with cored geometry r_obs >  r_bar. Top-right panel: same but for cuspy galaxies with r_obs <  r_bar. Also shown in both panels are the MOND MI curves for the two interpolation functions considered in Eq. (6). Middle-left panel: corresponding model curves for the cored galaxies from MOND MG curves using the Brada-Milgrom approximation with the g_bar and surface density Σ(r) values from SPARC. Middle-right panel: same as left but for the cuspy galaxies. For reference, the MOND MI curve is also shown again. Bottom-left panel: corresponding rotation speed curve data for two of the cored galaxies, compared to the MOND MI and MOND MG curves. Bottom-right panel: same as left but for two cuspy galaxies
