Notes. Column (1): name of the galaxy. Column (2): β parameter for three cases (isotropic, mildly tangential, and the literature-based, see text for details). Columns (3) and (4): Newtonian mass-follows-light models interior to 3Re and χ2 values. For the galaxies denoted in italics (NGC 4365 and NGC 4486), the inner regions are interior to 1Re and 0.35Re, respectively. Columns (5) and (6): Newtonian mass-follows-light models beyond 3Re and χ2 values. Columns (7) and (8): NFW models for the whole galaxy and χ2 values. Stellar mass-to-light ratio M∗/LB, rs, is in arcsecs, and ρs is in M⊙ pc-3. For galaxy NGC 5846, the regions where the fits were obtained were formed differently. For the constant mass-to-light models: “I” indicates the fit obtained interior to ~ 2Re, “II” indicates the fit obtained between ~ 2 and ~ 6Re, and “III” denotes the region beyond ~ 6Re. Column (9): mass-to-light ratios at 5Re. Column (10): mass-to-light ratios at rvir. The best-fits in this Table and in Table 7 are highlighted in bold characters and denote the best model among the three mass models (Newtonian-noDM, Newtonian-DM, and MOND-noDM).
