Temperature profile obtained from the R-L reconstructed emissivity profile via Eq. (6) with γ = 1.19 ± 0.04, compared to temperature profiles obtained using different techniques. Dark blue: profile derived from combined X-ray and thermal-SZ measurements (Planck Collaboration Int. V 2013) using the ideal gas assumption (Eckert et al. 2013); light blue: spectral fitting of XMM observations (Snowden et al. 2008); pink: spectral fitting of Suzaku observations (Kawaharada et al. 2010); red: mean value and errors on the reconstructed profile for γ = 1.19; gray: mean value and errors on the reconstructed profile for γ = 1.19 ± 0.04. The mean and the error bars were obtained with a Monte Carlo method based on the R-L deprojection. The reconstructed temperature profile has been normalized to the data points from Eckert et al. (2013) within a spherical shell delimited by the radii in the range [183; 2515] kpc.
