Variation in the anisotropy parameter β at selected radii of the final stellar profile: at the core radius r_c (the solid lines), within the core radius at r_c/2 (the dotted lines) and outside the core at 2 r_c and 3 r_c radii (the dashed and dash-dotted lines, respectively). Different colors represent different varying parameter as indicated in the inset. The absolute variation, given in the inset, has been normalized so that if p is the varying parameter then the abscissa represents (p − minp)/(maxp − minp). The gravitational potential set by DM is an Henon’s isochrone with an initial stellar velocity distribution that is isotropic (Sect. 2.2).
