MILCA Compton y-map of the area around two confirmed SZ sources, PSZ2 G066.34 + 26.14 (left, confirmed in this paper, SZ S/N = 5.6) and PSZ2 G066.41 + 27.03 (right, validated in Planck Collaboration Int. XXVI (2015), SZ S/N = 8.8), superimposed to a zoomed RGB SDSS images. The black contours correspond to the 3, 6, 9 × 10−6 levels of the Compton y-map in this area. The single black contour in the middle of the y-map corresponds to a noise fluctuation. The red circles indicate the nominal PSZ2 source locations. In the RGB SDSS images this nominal position is indicated with white filled circles. Both PSZ2 sources show the presence of clusters at similar high-z zphot = 0.62 and 0.53, respectively. Blue lines delimit the area corresponding to the peak of SZ signal for PSZ2 G066.34 + 26.14, which enclosed almost all cluster members. Scale bars in RGB images are 1′.
