Caption: Figure 3.

Correlation between errors for simulated galaxies, presented as the difference between (recovered – input) values for each parameter of interest: m, n, re, and q. Objects whose recovered magnitudes are brighter than the truth tend to have larger recovered sizes and Sérsic indices (upper left and middle left panels, respectively). Likewise, objects with a larger recovered n tend to have larger recovered re values (middle panel). There is no obvious correlation between the errors in the axis ratio with the other parameters (bottom row).
