The Abell 3651/3667 system as an example of overlapping CHANCES clusters (see Sect. 4.2). The symbols and colours are the same as in Fig. 5, but we do not highlight redMaPPer systems according to the CHANCES velocity dispersions. The circle colours are with respect to a reference z = 0.056, and the orange bar at the bottom right shows 5 comoving Mpc at the same redshift. The green contours show the eROSITA detection of hot gas within and between the clusters (Dietl et al. 2024).
