Sérsic index distribution (black histograms) for different redshift (from left to right) and ΔB_ev luminosity bins (from top to bottom). The blue and red solid lines show the Gaussian fits to the disc-like and spheroid-like populations, respectively. The vertical dashed lines mark the central values of each Gaussian. The sum of the two Gaussian fits is shown as a solid brown line. The central values ⟨ n ⟩ of the Gauss functions, their 1σ widths, and the total number of galaxies in each bin are shown in each panel.
