Stellar masses vs. sizes in kpc for cluster members inside (solid lines) and outside (dashed lines) R200. Left: the galaxies are classified into disk-dominated (blue) and spheroid-dominated (red) galaxies by their Sérsic indices. Disk-dominated galaxies closer to the cluster core are smaller at intermediate masses. Spheroid-dominated galaxies show little size variation in these two regimes. As before, lines represent mean values with their 1σ error bands. Right: MSR for star forming (blue) and quiescent (red) galaxies. Sizes of star forming galaxies differ marginally and only in one mass bin, whereas quiescent galaxies are consistently larger outside R200. This disagreement, as indicated by the 1σ error bands, is of the order of 1 to 3σ.
