Notes. For each object, we quote: the constraints on α at R500 and R200 both in Eckert et al. (2019) (second column) and in the present work (last column); the estimated Fi; the effective polytropic index, γ, measured in the radial range [0.3, 1.6]R500; the parameters 1/p0 = P0NT/P0T and β, from which α is estimated (see Eq. (8)). The quoted errors are at 1σ c.l., and the quoted errors on α are obtained from 100 Monte Carlo runs by propagating the statistical errors on the observed gas density and pressure profiles, and the observed gas fractions.
