Regions of the observations of Abell 2142 used in this analysis. Left: XMM-Newton X-ray data in counts (ranging from 0, in black; to 120 counts, in white), taken within the X-COP program (Eckert et al. 2017) (in logarithmic scale); right: Planck SZ data in units of the Compton-y parameter (ranging from 8.5e–7, in black; to 6.6e–5 counts, in white), using the method of Hurier et al. (2013). The black circle represents the position of the image center used in our analysis, while the two green circles outline R₅₀₀ and R₂₀₀.
