The density profile behaves as $r^{-\\gamma}$ in the inner parts, where $\\gamma \\simeq 1$ for the NFW model and $\\gamma \\simeq 1.5$ for the Moore's model, but in the outer parts, both models agree with each other in the asymptotic behavior of the density profile. The simulations also show the information about anisotropy parameter $\\beta(r)$ of velocity distribution. $\\beta\\approx 0$ in the inner part and $\\beta\\approx 0.5$ (radially anisotropic) in the outer part of the halo.
