Left: ratio of predicted flux (F_pred) to true flux (F_true) for BGRem (blue), SExtractor (red), and the input image (yellow), compared to the ideal line (black) as a function of the signal-to-noise ratio (S/N). Points represent individual sources: small points indicate stars, medium points galaxies, and large points elongated galaxies. Right: same as the left panel, but binned in S/N, with error bars representing statistical error.
