Fraction of MCXC2021 clusters recovered by tradition cluster detection methods in the SDSS (see text) from to bottom: MaxBCG, GMBCG, AMF, WHL09, and WHL12. The details of cluster recovery in each case are detailed in the text. In all cases, except WHL12, their completeness is worse than that reached by redMaPPer and YOLO–CL. These results, compared with Fig. 8 outline the high performance of our YOLO–CL with respect to traditional cluster detection methods in optical images.
