Illustration of the impact of a subtracted nucleus on the quantitative morphologies of the simulated AGN galaxies in concentration index C (upper left), asymmetry A (upper right), Gini coefficient G (bottom left), and M₂₀ (bottom right). As a function of H/N, all plots show the initial parameter value before (index ini) and after addition & subtraction of a synthetic nucleus (index sim), normalized to the initial value.
