Comparison of cluster parameters derived from our best fit of the isothermal beta-profile model in blue and estimated by PLIX2011 (Table 2) in gray. As the results for the polytropic NFW-profile model are almost the same, they are omitted for clarity. The blue thick and thin dash lines are the median and 1σ levels of our model. The gray areas show the 1σ levels of PLIX2011, except for R₅₀₀, which was not provided. Top, middle, and bottom rows: clusters A, B, and C, respectively. See Sect. 3.4.1 for more details.
