Table 2: Results of the stellar-mass estimate for the ellipticals sample, based of SEDs fitting with solar metallicity SSPs. For each elliptical source in the HDFS (Rodighiero et al. 2001), spectroscopic (Vanzella et al. 2003; Sawicky & Mallen-Ornelas 2003) or photometric (if within parenthesis, Rodighiero) redshifts, total number of models produced by the spectrophotometric synthesis code, best fit parameters and $\chi ^2$ for the analytic SFH method (see text for details), mass of the best fit solution and 2$\sigma $ (95.5% confidence) mass range due to degeneracies are reported. Third column reports a flag identifying red and blue sources. The SEDs of the red sources have been fitted with three different methods: a) analytic SFH, b) two simple stellar populations (109 and $1.2 \times 10^{10}$ yrs old) with solar metallicity, c) two old populations ( $1.2 \times 10^{10}$ yrs) with different metallicities (Z=0.02, 0.008) - see also text and Fig. 3. The mass ranges reported for these objects include the results of all three fitting tecniques; on blue sources only the analytic SFH leads to good results.
