FP dependences. TN and FP analysis related to the VGG and SC-VGG performances as a function of the galaxy lens photometry: F814W magnitude (left panel), (F606W − F814W)_norm normalised colour (right panel). In both panels, the TNs are plotted with purple and magenta lines, while the FPs are shown with red and orange lines (respectively for the SC-VGG and VGG): in both cases, solid for SC-VGG, dashed for VGG. The FPR is plotted at the bottom of each panel (as a purple line for VGG, red for SC-VGG). In both panels, only sources with available and reliable magnitudes are plotted.
