Redshift evolution (z = 0 (blue), z = 0.3 (orange), z = 0.5 (green), z = 0.8 (red), z = 1 (purple), and z = 1.4 (brown)) of the cumulative galaxy mass function for the LR_HYDRO (left), LR_DMONLY (centre), and HR_DMONLY (right) simulations for the four bin mass defined in Table 1 (from top to bottom). The shaded regions are obtained from the mean and standard deviation across clusters, as described in the text.
