Average pressure profile. Left: average rescaled harmonic transform Compton parameter joint measurement and best fitting gNFW model, with the REXCESS and PIPV profiles overplotted for comparison. The best fit (solid blue line) is close to the UPP at large lθ₅₀₀ (the central regions), and to the PIPV profile at small lθ₅₀₀ (the outer regions). Right: corresponding 3D pressure profiles. In both panels the dashed blue lines delineate the 68% C.L. uncertainties of our best fitting gNFW profile.
