Y6 CLUSTER MEMBERS WAZP (des_y6_gold.y6_cluster_members_wazp)
The table has -1 rows, 14 columns.
Description
This table lists galaxies assigned as members of WaZP clusters detected on DES-Y6 (Benoist et al. 2025). Each entry is linked to a cluster in y6_cluster_wazp via id_cluster. Membership probability Pmem is the weight used to compute cluster richness Ngals (sum of Pmem down to m*+1.5 within the cluster radius). The table includes positions, photometric redshifts, spectroscopic redshifts and sources when available, a flag for the central galaxy, and grizY magnitudes. Improved DES-Y6 depth and spectroscopic coverage support more accurate cluster redshifts and member assignments than the DES-Y1 WaZP release.
