The redshift evolution of the mass-to-light ratio for cluster (left) and field (right) galaxies. Top: black and red indicate galaxies with spectroscopic types 1 and 2, respectively. Morphologies for galaxies with HST photometry are coded as in Fig. 14. Galaxies with VLT photometry only are shown as crosses. Only galaxies with good VLT photometry (i.e., SExtractor flag 0 or 2) are plotted. The solid black lines show the solar metallicity SSP for zf = 2 (cluster) and zf = 1.2 (field). The solid red line shows the SSP for zf = 3.5 and half-solar metallicity, the cyan line shows the SSP for zf = 1.2 and twice-solar metallicity. The dotted line shows the best-fit linear relation (−0.55z for cluster and  −0.76z for field galaxies) and the 1σ errors dashed. Bottom: the blue points show averages over redshift bins 0.1 wide. The cyan points are average field galaxies from van Dokkum & van der Marel (2007). Only field galaxies (plot to the right) with dynamical masses higher than 1011   M are considered.
