Left: wavelet-smoothed XMM-Newton photon-count image of the cluster. The region is the same as for the NIKA2 maps in Fig. 1. The isocontours are shown in grey. Right: electron density (top) and temperature (bottom) profiles extracted from XMM observations of the cluster. The profiles are extracted at the SZ surface brightness peak; see Sect. 3.2. Error bars are 1σ. For the temperature profile, the red line shows the projected temperature, and the white points represent the reconstructed 3D profile; see Pratt et al. (2010) for a detailed explanation of the difference.
