Input vs. output fluxes of the simulated sources, from 100 2 − 10 keV simulations. Only sources with a match within 6″ are considered. Some outliers are present, due to EMLDetect uncorrectly associating the source with extended emission especially in crowded regions, and for which we rather use the PWXDetect fluxes; the number of outliers is a few per simulation. The red line shows the identity relation. At bright fluxes ( ≳ 10^-14 erg s^-1 cm^-2), the output values are about 20% larger than the input ones.
