Table 7: Observed evolution of the lens, as a function of the underlying assumption on $\sigma _{\rm c}$: FJ or GL model with possible correction for central velocity dispersion ( $f_{\rm SIE}$) and typical environment (Env).

Hypothesis		 $\sigma_c$ (km s-1) $\Delta \log (M/L)_r$

GL		 $355\pm35$ $0.01\pm 0.06$
GL+ $f_{\rm SIE}$ $309\pm28$ $-0.1\pm0.08$
GL+ $f_{\rm SIE}$+Env $291\pm26$ $-0.14\pm 0.08$
FJ $251\pm 29$ $-0.24\pm 0.08$
