**Table 4:** 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 2 and the PÉGASE.2 grid of evolutionary sequences defined in Table 3. 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 (2001), these values should be multiplied by a factor of $\approx$ 0.6, as discussed in Sect. 4.3.
