Stellar mass and SFR. Top and middle: SFR versus stellar mass from Chang et al. (2015) for the PSS-CSO and the ECS samples. The colour coding of the symbols is the same as in Fig. 14, filled squares signify galaxies with good model fits. The cyan curves are local density contours maps for ∼9 × 10⁴ SDSS galaxies. The black lines indicate the SF sequence (solid) and the 3σ scatter (dashed), the blue lines are the corresponding extrapolations to log M_*/M_⊙ = 12. Bottom: Histogram distributions of the SFR for the PSS-CSO (blue) and ECS (green) galaxies with FLAG = 1.
