## Description

17 pairs (A+B) of simulations with different values of  $\Omega_{M}$  &Omega; . Simulations have $512^3$ dark-matter particles in a comoving cubic volume of $500h^{-1}$Mpc on a side. 
Values of $\Omega_{M}$ range from $0.10$ to $0.50$, equally sampled in intervals of $0.025$. 
Simulations were run with Gadget-4 [1], using power spectra generated with CAMB [2]. In all cases we use 
fixed comological parameter for $\Omega_b = 0.05$, $h=0.67$, $\sigma_8 = 0.81$, $n=0.96$ and 
$\Omega_{\Lambda} = 1 - $\Omega_M$. The A+B pair follows the paired-fixed approach to suppress cosmic variance [3].
