Non-parametric pressure profile (blue) deprojected from the NIKA tSZ surface brightness map and the Planck Compton parameter map. The 3 radial bins at 3, 4, and 5 R₅₀₀ are mostly constrained by the Planck data. A gNFW pressure profile model has been fitted on the NIKA+Planck deprojected pressure points (black solid line). XMM-Newton estimated pressure profile (red) based on the deprojected density profile and the temperature estimation from spectroscopic observations. The NIKA/Planck and XMM-Newton estimates are compatible within error bars.
