Table 1: Properties of the two simulated halos we used. $z_{\rm l}$denotes the redshift of the halo, $z_{\rm s}$ is the redshift of the source. $N_{\rm bar}$, $N_{\rm DM}$, and  $N_{\rm str}$ are the numbers of baryonic, dark matter particles and "stars'', respectively, present in the cut-out of the simulation we used (note that even within one family particles have different masses). $M_{\rm tot}$ is the total mass of the particles we used.
