Top panel: intracluster gas mass profile (lower curve) and the hydrodynamical derived total mass radial profiles. The gray-shaded regions represent 1σ confidence levels. Vertical lines indicate r_image, the limit where the cluster is detected with the combined XMM data (using both exposures), and r₅₀₀ and r₂₀₀, computed from the X-ray derived mass profile. Bottom panel: gas mass fraction radial profile. As a reference we also show the universal gas fraction, as obtained by the cosmic baryon fraction Ω_b/ Ω_m value from WMAP-9yr (Hinshaw et al. 2013) and Planck 1st release (Planck Collaboration XVI 2014, including their uncertainties), reduced by 17%.
