Dynamical properties of the n = 2 Einasto model with an Osipkov-Merritt anisotropic orbital structure. All lines correspond to an Einasto model with exactly the same density profile with M = r_h = 1 and n = 2, but with a different value for the anisotropy radius r_a, as indicated in panel a. Solid lines are consistent dynamical models, dashed lines are unphysical dynamical models. The critical value for the anisotropy radius for this specific Einasto model is (r_a)_c = 0.2313 (see Table 1). (a) Radial velocity dispersion. (b) Tangential velocity dispersion. (c) LOS velocity dispersion. (d) Distribution function.
