Distributions, in the redshift range 1.5 < z < 2.8, of stellar age, stellar mass, and SFR computed by SED fitting (using Maraston 2005 models with a Kroupa IMF) for: the final sample of 74 objects analyzed in this paper (shaded red histogram); the GMASS total sample (open histogram); and objects with a secure redshift determination from the GMASS spectroscopic sample (shaded black histogram). Medians of the photometric catalogue and the 74 SFG sample are also shown (vertical black and red lines, respectively).
