Notes. For all of the simulations we used, ΩK = 0, ns = 0.9630, h = 0.72, L = 648 Mpc/h and N = 20483 particles. In addition, for initial power spectrum computation, Ωb = 0.04356 (and baryons are then supposed to follow DM dynamics). The σ8’s are the rms fluctuations at 8 Mpc/h, computed on the power spectrum linearly extrapolated to z = 0, and using a Gaussian W(x)=expx210$\[W(x)=\exp -\frac{x^{2}}{10}\]$ or a Bessel W(x)=$\[W(x)=\]$ 3sin(x)xcos(x)x3$\[3 \frac{\sin (x)-x \cos (x)}{x^{3}}\]$ window function. δc is the critical spherical overdensity at z = 0.
