Fig. A.1

Photometric versus spectroscopic redshifts for the cluster galaxies in our sample. Black lines give the perfect relation of slope 1 and the ±0.15 × (1 + z) classical uncertainty (see e.g. Ilbert et al. 2006). Red filled circles are early-spectral-type galaxies and blue filled circles are late spectral-type galaxies (see text).
