Radial density profile. Mass resolution analysis of the three-sine-wave PM simulations with ϵ = (3/4, 1/2). This figure is analogous to Fig. 17, except that it focuses on the effect of changing the number of particles in the N-body runs. All the simulations have the same spatial resolution, n_g = 512, but different values of n_p, namely n_p = 512 (black, PM-ANI2-HR), 256 (red, PM-ANI2-MR), and 128 (blue, PM-ANI2-LR). In the right panels, the ratio considered is ρ/ρ_PM, 512, where ρ_PM, 512 is the density measured in the PM run with n_g = n_p = 512 corresponding to the black curves.
