Illustration of the impact of an unsubtracted 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, both plots show the initial value before (index ini) and after the addition of a synthetic nucleus (index unsub), normalized to the initial value. See text for a discussion.
