A2163-A profiles associated with the overall cluster (in black) and the eastern and western cluster sectors shown on Fig. 7 (in red and blue, respectively). Top: gas surface brightness (left) and projected temperature profiles (right). Bottom left: ICM pressure profiles modelled to fit surface brightness and projected temperature. Bottom right: ICM pressure profiles re-scaled to the characteristic pressure of a self-similar cluster with mass M₅₀₀. The distribution of scaled pressure profiles measured in a representative sample of nearby galaxy clusters (REXCESS, Arnaud et al. 2010) has been overlaid in light blue.
