Results of the fit of 200″ × 200″ cutouts of the NIKA2 COSMOS 2 mm map centered on two cluster candidates. NK2-CL J100004.4+021148.4 (top) has a known redshift z = 0.94. In contrast, for NK2-CL J100045.8+020514.3 (bottom) we found no counterpart. The left map corresponds to the 1.2 mm map centered on the cluster candidate. Then, from left to right, we show the 2 mm cutout map for the cluster candidate, the best-fit tSZ model, and residuals. For visualization purposes, the maps have been smoothed with a Gaussian 2D kernel of 6″ and 10″ for the 1.2 mm and 2 mm maps, respectively. The effective FWHM for the 1.2 mm and 2 mm maps is represented as a black disk in the bottom left corner. The white contours have the same scaling as in Fig. 6. We observe that the tSZ effect at the cluster position is negative in the 2 mm band, and not observed at the 1.2 mm band, as expected.
