Quality of the flux measurements made by getsf when sources are both detected and extracted in the original image (in a), detected in the denoised and measured in the original images (in b), and both detected and measured in the denoised image (in c). The ratios of the getsf integrated fluxes to the true fluxes are plotted for individual sources, arranged in decreasing mass bin (main panel) and median values for the nine mass bins (enclosed plots). Blue hatched regions represent fraction of the truth table sources undetected by the algorithm, for each mass bin. For cores down to the 0.28 M_⊙ bin, fluxes are correct by ~10% for the three extraction runs. The denoised image provides a catalog with 40% more sources whose flux measurements are, for 90% of them, better than a factor of 2.
