Selection curves in the KS-test probability-S/N plane (magenta solid line). The color–coded grid indicates the absolute value of the number of unresolved minus the number of extended sources. Regions dominated by unresolved sources are depicted in blue, while regions dominated by extended sources are shown in red. The selection curve has been defined as the loci of zeros on the grid. The cyan line refers to a KS-test probability of 50%.
