\caption {Results for integrated quantities for the cluster, in the monolithic 
approach. 
{\it  Column 1}: IMF of model galaxies.
{\it Column 2}: redshift of formation of galaxies.
{\it Column 3}: global $IMLR$ for the cluster.
{\it Column 4}: global $M/L$ ratio for cluster galaxies (ratio between
		       the global mass in "galactic remnants'' and the global
		       $B$--luminosity).
{\it Column 5}: ratio between the mass of gas ejected as GW and the 
                    	   global $B$--luminosity of cluster galaxies.
{\it Column 6}: ratio between the mass in gas ejected as~GW and the 
                    	   mass in "galactic remnants''.
{\it Column 7}: iron abundance with respect to solar in the gas ejected
		       as~GW.
{\mbox{\it Column 8}}: fraction of the global iron production contributed
              	    	         by SN~Ia.
{\mbox{\it Column 9}}: [O/Fe] ratio in the gas ejected as~GW (and hence
		              in the ICM).
{\it Column 10}: "dilution factor'' necessary to recover the observed
${ICMLR}=M_{\rm ICM}/L_{\rm tot}=37~M_{\odot}/L_{\odot}$ (see text).
{\it Column 11}: ratio between the total mass of~ICM gas and the mass
		        in galaxies.
{\it Column 12}: average iron abundance in the ICM~gas.
