Jeans models for the blue GCs (BlueFinal) for an NFW-type dark halo. From left to right, the panels show the results for β =  −0.5,0 and  + 0.5. The parameters are shown in the (M_vir,c_vir)-plane. The thick solid, dashed and thin solid lines indicate the 68,90, and 99 per cent confidence limits. The colour map is the same for all panels, and the cross indicates the location of the minimum χ² value. The square shows the minimum χ² for the joint models obtained from the blue GCs and an isotropic model for the NGC 4636 stellar dispersion profile. The circle indicates the respective best-fit value from Paper I. All model parameters are listed in Table 9. In all panels, the long-dashed (dash-dotted) lines show the median (68 per cent values) for simulated NFW halos as found by Bullock et al. (2001).
