Fig. 18

Best-fit of the mass-size relation in Eq. (6) for early-type passive low-mass galaxies (M⋆ ≤ 1010M⊙; upper panel) and high-mass galaxies (M⋆> 1010M⊙). The best-fit values of the two parameters a and b with their 1σ uncertainty are given in the two panels. Dark blue points identify spectroscopic members, while light blue point are photometric members.
