Notes. Column (1): name of the galaxy. Column (2): Newtonian model without DM for the internal part (interior to ~ 3Re). Column (3): Newtonian model without DM for the exterior part (exterior to ~ 3Re). Column (4): stars + NFW DM model (for the whole galaxy). Column (5): MOND models without DM for the internal part (interior to ~ 3Re). Column (6): MOND models without DM for the exterior part (exterior to ~ 3Re). Here, the sign “√” denotes that a given model can provide a successful fit to the observed data. The sign “−” denotes that the given model cannot provide a successful fit to the observed data. The sign “~” for galaxy NGC 2768 denotes that this galaxy can be fit with a constant mass-to-light ratio, but the value obtained is marginally higher than that predicted by SPS models. The combination of signs (“√ −”) for NGC 4494 denotes that the mass-to-light ratio obtained for this galaxy in its outer parts is consistent with the value obtained using SPS models. Because of the increase of the mass-to-light ratio in its outer part, however one cannot exclude the existence of DM (see text for details).
