\caption {\label{alphayz}First 4 rows: ages (measured in Gyr), metallicities [Z/H] and [E/Fe] 
abundances for the stacked spectra, in different redshift bins, 
of the red-sequence galaxies, measured using V08 models and the indices H$\gamma_{\rm F}$, Fe4383 and
CN$_2$. The spectra have been stacked separating galaxies with 
$\sigma$ lower than 175~km~s$^{-1}$ (right side) and larger than 175~km~s$^{-1}$ (left side). The parameters have been obtained iteratively as
described in the text. Last three rows: ages, metallicities
 and [E/Fe] derived for the stacked spectra, at different redshifts, of
morphologically classified E and S0 galaxies.}
