\caption{The range in age, $M/L_V$ and $M_\star$ allowed by the acceptable fits to the observations at the $1\sigma$ and $2\sigma$~levels using the Z01 grid of evolutionary sequences defined in Table~\ref{modelgrid} and the P\'EGASE.2~grid of evolutionary sequences defined in Table~\ref{modelgrid2}. Only the results from sequences assuming a Salpeter~IMF with $M_{\rm up}=120~M_\odot$ have been included. Missing entries indicate the lack of acceptable fits at a given confidence level or, in the case of~$M_\star$, the lack of redshift data for a particular object.  To obtain values of~$M/L_V$ and~$M_\star$ consistent with the observed IMF of Kroupa (\cite{Kroupa}), these values should be multiplied by a factor of~$\approx$$0.6$, as discussed in~Sect.~4.3.}\label{constraints_Z01+Peg2}
