The five-component artificial stack from Fig. 5 compared to the CDFS 7 Ms catalogue within a 10′ circle. From left to right: all XMM-Newton detections, those with a Chandra match within 5″, fraction of detections without Chandra counterpart, and Chandra full-band fluxes of the matches. Dark blue bars denote the results from stacked source detection, light blue bars those from source detection on the individual sub-exposures, and orange cross-hatched bars their joined source lists.
