NIKA maps at 150 GHz (left) and 260 GHz (right) in units of surface brightness. The significance is given by the black contours starting at ± 2σ with 1σ spacing. The maps are smoothed with an extra 10 arcsec Gaussian filter for display purposes and the effective beam FWHM is represented as a white circle in the bottom left corner of each panel. The white crosses indicate the X-ray center.
