Isotropic Jeans modeling of the projected velocity dispersion of NGC 4472 using a Newtonian approach: mass-follows-light (M/LB = 10) and NFW models are shown. One effective radius is indicated by a vertical dotted line. Solid and dashed lines are plotted using vrot = 50 kms-1. A scaled-up version of the Newtonian mass-follows-light with M/LB = 15 is plotted with a thin solid line. Two hatched regions (the upper one is for the NFW model and the lower one is the Newtonian constant mass-to-light ratio model with M/LB = 10) for each approach take into account various values of the rotational velocity: the lower limit in both cases is for vrot = 28 kms-1 and the upper limit in both cases is for vrot = 105 kms-1.
