Projected gravitational potential reconstructed using the method described in Konrad et al. (2013) compared to the potential recovered from weak gravitational lensing as a function of the projected radius s. The projected potential reconstructed from the X-ray emission has been obtained assuming a polytropic index γ = 1.19 ± 0.04 (see the text for details). The potential recovered by lensing is shown in blue; the mean projected potential obtained from X-ray observations with γ = 1.19 ± 0.04 is shown in red, the uncertainties of the latter are shown in gray. The mean and errors have been obtained using a Monte Carlo method to randomize the algorithm described in Konrad et al. (2013). The reconstructed lensing potential has been normalized to the lensing data within a circular shell region delimited by the radii in the range [92; 1734] kpc.
