Completeness profiles within the three different extent likelihood cuts (i.e. ℒ_EXT > 3, 6, 10). The completeness is defined in terms of the input flux S​₅₀₀ in the soft band (0.2 − 2.3 keV) in the top panel and the halo mass M₅₀₀ in the bottom panel. We present the results for the sample with the extended (primary) detections with the solid lines. The dashed-dotted grey lines show the fraction of misclassified point sources: they are detections from the point source catalogue whose X-ray emission is at least 80% the IGrM in input. The coloured dotted lines are the best-fit curves.
