Measured G (top row) and M₂₀ (middle row) for the EGS images at 0 < z < 2 as a function of n. In each panel, the dashed black line shows the median trend for the R_e/FWHM > 5 sub-samples at z < 1 (left two columns), with the grey-shaded region indicating the 16th to 84th percentile range of the variation. The distributions of galaxies in our sample at different redshift ranges in the G-M₂₀ space are shown in the bottom row, colour-coded by the Sérsic index. The dashed lines are the boundaries between different galaxy types (Merger, E-Sa, and Sb-Irr) derived from Lotz et al. (2008).
