Radial mass profile derived from the X-ray data, where the hydrostatic mass profile and uncertainties are shown by the solid line and the grey area. Error bars represent the 1σ uncertainties described in the text. Also shown are the mass profiles derived from the WL analysis (dashed line: NFW fit; points with error bars: aperture densitometry after deprojection). The inset shows M₂₅₀₀, M₁₀₀₀, M₅₀₀, and M_vir derived from our XMM analysis (blue squares); the Planck analysis (green squares); WL NFW, first row in Table 2 (red triangles); WL, aperture densitometry (black circles): a small offset in radius is applied here for display purposes.
