Left: distributionin the M₅₀₀-z planeof the 1094 PSZ2 clusters with counterparts with known redshift. New PSZ2-detected clusters are indicated with red dots, while commmon PSZ1 and PSZ2 clusters are indicated by black dots. The solid, dashed, and dotted lines indicate, respectively, the 20%, 50%, and 80% survey completeness contours for the PSZ2. Right: distribution of the PSZ2 clusters with associated redshift in the M₅₀₀−z plane compared to the SPT (Bleem et al. 2015) and ACT (Hasselfield et al. 2013) catalogues. Black circles represent PSZ2 clusters, while red and green filled circles mark common SPT/PSZ2 and ACT/PSZ2 clusters, respectively. The remaining SPT and ACT clusters not detected by Planck are shown with red and green empty squares.
