χ ² curves for all parameterizations of the mass profile. NFW halos (blue) are parameterized by concentration c and scale radius r _s . Logarithmic halos with an IMBH (green) and without an IMBH (red) are specified by V _c and r _c , respectively. We also plot core density ρ _c = 3 V ² _c /4π Gr ² _c as it is the controlling parameter over the radial range of our models. We fit for stellar M/ L _V in all models (upper left panel). NFW models have much higher χ ² and are scaled down by 75 to fit on the same axis. Black hole mass for logarithmic halos with an IMBH (green) is plotted in the upper right panel. Note that the apparent minimum in r _c for logarithmic halos with an IMBH is due to incomplete parameter sampling.
