Offsets of cluster galaxies with different morphologies from the MS at z ~ 0.4. Blue squares are disks, red circles smooth, black compact, and green irregulars. The red solid lines show the MS at z ~ 0.4 predicted by Peng et al. (2010a). The shaded area is the 1σ scatter of the respective morphological category, while the dashed thick black line is the median value.
