Distribution of the stellar masses and of the structural parameters obtained from the r-band KiDS images. From left to right: histograms of the total stellar masses in units of 10¹¹ solar masses and bins of 0.1 (calculated in S20), r-band sizes in arcseconds with bins of 0.03, the Sérsic indices (n) with bins of 0.3 and axis ratios (q) with bins of 0.05, both in r-band (computed in Roy et al. 2018).
