The three couples of profiles below have been divided by 10², 10⁴, 10⁶ for clarity. We also show a NFW density profile having a concentration parameter $c \approx 23$ (dotted line), obtained as a two parameter best-fit of the density profile of simulation c5 at z=0. Length units are in physical kpc.
