Caption: Fig. 6.

Velocity dispersions, in radial bins, for the final halos. Shown is the radial velocity dispersion σ_r (top) and the velocity anisotropy parameter ﹩\beta =1-\sigma ^{2}_{t}/ \sigma ^{2}_{r}﹩ (bottom). The halos with constrained radial accelerations are the upper velocity dispersions in the top panels and have ﹩\beta \sim 1﹩ in the bottom panels.
