Fraction of galaxies in the four categories of age and SFR classification, based on the aperture-corrected physical parameter estimates: star-forming-old (black), star-forming-young (hatched blue), passive-old (hatched red), and passive-young (green). The vertical dot-dashed line identifies the transition mass between star-forming and passive galaxies, obtained from the mass-functions in the right panel of Fig. 10. The vertical solid line identifies the transition mass between young and old galaxies, obtained as described in Sect. 4.2.
