Summary plot for the single-Sérsic simulation. The different rows show the results for the three different structural parameters: half-light radius r_e (top), axis ratio q (middle) and Sérsic index n (bottom). Columns represent (1) the mean bias ℬ, (2) the dispersion 𝒟, and (3) the fraction of outliers 𝒪, per bin of I_E magnitude (see text for details). We note that the y-axis is sometimes cut at low values to highlight the small differences between the software packages. Each code is plotted with a different colour as labelled.
