Mass-SFR diagram, with the values obtained by the various stellar population models plus the IR-inferred SFRs (red circles: Calzetti-based exponentially declining models with nebular emission; green diamonds: same but with SMC; upwards blue triangles: the classic models assuming Calzetti, constant SFR, and t_min = 100 Myr; downwards purple triangles: IR-inferred SFRs vs. mass from SFR = const. model; black hollow diamonds: energy conserving models). Also plotted are the Daddi et al. (2007) main sequence for z ~ 2 from the GOODS field (grey continuous line), and the relation 4 times above this main sequence as shown in Rodighiero et al. (2011) (grey dot-dot-dashed line).
