NIKA2 maps of CL J1226.9+3332 at 150 GHz (left) and 260 GHz (right) in Jy beam⁻¹ units. Contours show S/N levels in multiples of ±3σ. Both maps have been smoothed with a 10′ FWHM Gaussian kernel. The position of the X-ray centre is shown as a magenta cross in the 150 GHz map and the elongation of the tSZ signal towards the south-west is indicated by the white arrow. White and red circles in the 260 GHz map show the submillimetre and radio point sources, respectively.
