Table 2
Fits for the Newtonian (constant mass-to-light ratio and NFW models) and the MOND isotropic models (assuming vrot = 50 kms-1) for two different binnings (“a” and “b” as described in Sect. 2.1).

Notes. Column (1): the name of the model. Column (2): mass-to-light ratio in the B-band used. (∗) For the NFW model, the mass-to-light ratio is given for the outermost point (binning “a”): note also that this value refers to the dynamical mass-to-light ratio, whereas in all other cases in this table the dynamical mass-to-light ratio and the stellar mass-to-light ratio coincide. Column (3): reduced χ2 of the fit for a given model (see text for details).
