Left panel: distribution of sources in the SFR − z plane, analogous to Fig. 1. Cyan points and magenta crosses indicate the distributions of disk- and spheroid-dominated subsamples of star-forming galaxies, as defined in Molnár et al. (2018). The 3σ contours of the CSFG sample are shown as black lines, and the orange rectangle marks the edges of the chosen nearly complete disk- and spheroid-dominated samples. Right panel: their respective SEDs.
