Space telescope – real images for completeness & purity (GSDEEP and HUDF09). On the x-axis, the magnitude at which the purity drops below 90%, on the y-axis the magnitude at which the completeness drops below 50%. Each symbol is referred to a different denoising method, which can be present multiple times in the plot due to different combinations of detection parameters, see text for details. The positions of the symbols are slightly randomized to improve readability.
