Solid lines show the contour density map for the distribution of SXDF2018 galaxies in the SFR–M diagram; this is fit by Eq. (8) as described in Sect. 4.3 (dashed line). Filled circles are SFR median in running bins of galaxies with SFR_SOM/M_SOM >  10⁻¹¹ yr⁻¹ (orange symbols) and f_Q <  0.5 (red). In both cases, error bars are calculated with the 16th–84th percentile difference. The red circles are interpolated by a linear function (dotted line).
