Correlation between concentration and stellar mass. Here and in all subsequent figures with this color scheme, we show ETGs (T ≤ 0) color-coded by T-type, while we show all S⁴G galaxies in gray. We show dwarf ETGs (T = 11) in cyan. The dashed black line shows a linear fit between log (ℳ_*/ℳ_⊙) and log (n), converted from C₈₂, for ETGs (Eq. (7)). The red dashed line shows a similar fit, but here n was estimated for each ETG via single-component 2D decompositions (Eq. (8)).
