Scaled mass profiles of all the clusters of our sample, derived assuming hydrostatic equilibrium (HE). All calculations used the combined XMM-Newton-Chandra density profile, and full details of the mass calculation methods are given in Sect. 2.4.1. Various methods give very consistent results in the radial range with temperature information, but may diverge at small and large radius in spite of the density information. For each panel: the black points represent the mass profiles obtained from the forward non-parametric-like method, using the HE equation and the non-parametric-like temperature profiles shown as black points in Fig. 1. The blue and red solid lines represent the fit of these forward non-parametric-like profiles using a NFW and an Einasto model, respectively. The grey area is the mass profile computed assuming hydrostatic equilibrium and using the parametric temperature profiles shown with a grey area in Fig. 1. The blue and red envelopes represent the mass profile computed using the backward method, i.e. fitting the observed temperature profile with a model derived from the HE equation and assuming a NFW and an Einasto profile, respectively, for the underlying total mass distribution. The parametric mass profiles are estimated in the wider radial range covered by the density profile.
