Planck maps and background templates of PSZ2 G271.18-30.9 from the 100 GHz (first column), 143 GHz (second column), 217 GHz (third column), and 353 GHz (fourth column) channels. The first and second rows show the raw and the cleaned maps, respectively. The third row shows the CMB templates, the fourth row the Galactic dust templates. Red circles mark r₅₀₀ and the black circles represent the beam FWHM of each channel. The map size is 12r₅₀₀ × 12r₅₀₀ and the axes show the distance from the cluster centre in arcmin. The pixel size is 1 arcmin.
