Comparison of redshifts, ages, metallicities, and stellar masses between the spectroscopic study of Gallazzi et al. (2005), Y-axis, and the stellar populations retrieved from ALHAMBRA with BC03 models, X-axis. In red, we present the galaxies for which our techniques establish that they may have large extinctions: intermediate extinctions in green and low extinctions in blue. The dashed black line indicates the one-to-one relationship. The solid black line shows the fit between spectroscopic and photometric ages, accounting for the uncertainties in both measurements. The black crosses represent the average uncertainties of both techniques at different ranges. The star-shape markers are the galaxies with a radial size below 2″.
