SFR–M_* relation, colour-coded by the median A_V (top), T₀/τ (middle-top), Sérsic index (middle-bottom), and Sérsic radius (bottom) of objects in each bin. A bin is coloured only when the number of sources falling within the bin is higher than 20. The contours in grey contain 90%, 50%, and 10% of the full sample. The literature SFMS are the same as the ones shown in Fig. 9 and reported in Sect. 4. Dashed lines highlight the loci of equal sSFR.
