Radial profiles of the average enclosed dark matter density ρ (< r) centered on the location of the potential minimum, starting at the radius enclosing at least 20 particles. The vertical dotted lines indicate the softening lengths, _soft = 124, 124, 40, and 60 pc for Eris, ErisDark, VL2, and GHalo, respectively. The location of the maximum enclosed density (for r > _soft) is denoted with a filled circle. Dotted lines show the best-fit Einasto profiles (fitted to 1 kpc < r < R _vir), whose parameters are given in Table 1.
