Comparison between the Planck and XMM-Newton derived deprojected total pressure profiles. Upper panel: blue line and light blue shaded region are the deprojected pressure profile, with its 68.4% confidence level errors, obtained from the X-ray analysis of the XMM-Newton data (see text). The black line and grey shaded regions are the best-fit and 68.4% confidence level errors from the Model C pressure profile resulting from the fit shown in Fig. 5. Lower panel: ratio between the XMM-Newton and Planck derived pressure profiles. The black line and the grey shading indicate the best-fit and the 68.4% confidence level errors, respectively.
