Evolution of the average SFR of star-forming galaxies with mass and redshift. Our results from stacking are shown as colored filled circles, the colors corresponding to the different redshifts as indicated in the legend. We complement these measurements by stacking sliding bins of mass (see text) for visualization purposes only to better grasp the mass dependence of the SFR. In the background, we show as light gray curves our best-fit relation for the main sequence (Eq. (9)).
