\caption{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.}
