Comparison to the NFW halos derived by Johnson et al. (2009) with the parameters listed in Table 10. Upper panel: velocity dispersion profiles. The data points show our final blue GC sample (same as in Fig. 19, left panel but for a distance of 16 Mpc). The thick solid line shows model J1; model J2 is shown as short-dashed line, the dashed regions show the corresponding uncertainties. The long-dashed line is model J3, and the grey area shows the uncertainties. The dash-dotted line (labelled X_ab) corresponds to the mass profile (incorporating the abundance gradient) shown in Fig. 4 of Johnson et al. The thin solid line is the best-fit model for the GCs (r_s = 20   kpc, ϱ_s = 0.012, Υ _⋆ ,R = 6.4). Lower panel: circular velocity curves. The line styles are the same as in the upper panel.
