\caption{Cosmological and gas physics parameters used in the simulations. Densities relative to critical density are labelled~$\Omega$. $\Omega_{\rm tot}$ is the density of universe, all components included, $\Omega_{\rm b}$ is the baryon density, $\Omega_{\Lambda}$ the vacuum energy density, $\Omega_{\rm DM}$ the dark matter density. $h$~is the reduced Hubble constant, $n_{\rm s}$ the spectral index of primordial density power spectrum, $\sigma_8$ the rms~density fluctuations in spheres of~$8~\rm MPc$ diameter, $f_{\rm Mass}$ the mass function used in cluster abundance computations, $T_{\star}$ the cluster mass-temperature normalisation factor, and~$f_{\rm g}$ the cluster gas mass fraction. The double vertical line destinguishes the primordial cosmological parameters, from the ingredients of the structure formation semi-analytic model. }
