eFEDS clusters. Each panel shows a different cluster with the relative name, redshift (z), richness (λ), and mass (M_500c). The optical image is an RGB cube built from HSC data using the g, r, and z bands. The green lines denote the 3σ contours of the X-ray emission. The green cross identifies the X-ray center found by eSASS, the blue one denotes the position of the galaxy with the largest membership probability, and the pink plus sign locates the optical center identified the centering algorithm of redMaPPer.
