Size-mass relation for galaxies separated by d_cl for (a) red, (b) blue, (c) elliptical, (d) disk, (e) red elliptical, (f) red disk, (g) blue elliptical, and (h) blue disk galaxies. The galaxies with d_cl in [0, 2], [2, 10], [10, 30], and [30, 50] Mpc are plotted in red, orange, green, and blue, respectively. The error bars are the dispersion in the likelihood fitting. The gray thick lines show the size-mass relation for all the pz samples. Only the mass bins containing more than 50 galaxies are plotted. The red points represent cluster galaxies with insufficient numbers to determine the mean size.
