First five panels: 3D temperature profiles. Blue and orange rectangles are profiles determined using XMM-Newton and Chandra datasets, respectively. Filled and empty boxes represent profiles computed using the X-ray peak and the BCG as centre, respectively. Bottom right panel: 3D X-ray peak-centred temperature profiles scaled to their global T_X values. The solid black line shows the average value of the REXCESS temperature profiles (Pratt et al. 2007; Arnaud et al. 2010, APP10). Profiles are colour coded according to the mass estimated from M_500,YX, the most massive being red and least massive being blue.
