Left: the fraction of clusters as a function of mass and X-ray luminosity in the semianalytic model (colour coded contours), along with the position of cluster ClG 0332-2747  in the M − L_X plane: the black filled square is derived from the full galaxy sample, the green one from red-sequence members only (see main body for details). Blue symbols and error bars are the clusters from the literature represented in Fig. 6. Right: the fraction of clusters as a function of virial temperature and M_star/M_gas ratio in the semianalytic model (colour-coded contours), along with the relevant quantities for cluster ClG 0332-2747  (black and green squares) and for the clusters in the sample by Dai et al. (2010) (blue).
