Notes. In the second column the data used to constrain the mass are listed; PSZ and TX refer to the SZ pressure and the X-ray temperature, respectively; the subscript “NO3” indicates that the first three Planck points were not used in the analysis; the subscript “SYS” indicates that the systematic uncertainties on the X-ray temperature are added in quadrature to the statistical errors in evaluating the χ2 (see Sect. “Systematic uncertainties on the temperature profile”); “Median” or “Mean” refers to how we computed the X-ray emissivity; “β fixed” indicates that the outer slope of the pressure profile is fixed to the best-fit value of the Planck Collaboration. In the other four columns, we quote the results on M200, R200, M500, and R500, respectively. In the first row, we indicate our reference values in bold. The last two rows present the mass reconstructed using the mean density profile, and propagating the statistical error on the temperature profile only (see Sect. “Systematic uncertainties on the temperature profile”). RΔ is defined as .
