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.
