Sky distribution of CHANCES clusters in equatorial coordinates in a Mollweide projection. The radius of each circle corresponds to the maximum between 5r₂₀₀ and 1 deg (the latter set for visibility) and is colour-coded by redshift. The supercluster regions are shown with green polygons. The region below the red curve corresponds to the eROSITA-DE survey, the dark orange region shows the approximate LSST survey area, and the light orange region shows SO-LAT and CCAT-WFS (for simplicity, we draw both as delimited by −60° ≤δ ≤ +18°). The grey band bounded by black lines shows Galactic latitudes |b|≤20°.
