(S/N)_WL of the clusters and groups detected by AMICO in the XXL-North field of HSC-SSP. Top: (S/N)_WL as a function of redshift and richness. The (S/N)_WL is computed as the median value for the candidate groups in the bin, and (S/N)_WL is colour-coded as shown in the right bar. The number of candidates is superimposed in each bin. Bottom: Same as in the top panel for (S/N)_WL as a function of redshift and (S/N)_det. In other words, this panel shows the S/N of the optical detection of the algorithm.
