Initial density profile corresponding to a γ = 0 (top) and a γ = 1 (bottom) model (filled orange squares) and corresponding density profiles at t = 10³t_c in the self-consistent and tracers in smooth potential simulations (upward blue triangles and downward magenta triangles, respectively). The dashed black lines mark ρ(r) as given in Eq. (5). The points correspond to the same simulations of Fig. 3.
