Notes. For this analysis the central cluster emission inside a radius of was excised to avoid any influence of cluster cool cores. The power ratio parameters have been determined for an aperture with a radius of R₅₀₀. The corresponding results without center excision are given in Table A.1 in the Appendix. For each of the power ratio parameters we provide the value of the noise contribution to the power ratio result (bias) which has been subtracted from the measured result to provide the value listed in Cols. 2, 5, and 8. The uncertainties determined from the Poissonisation simulations are listed in Cols. 4, 7, and 10 (error). The center shift statistic parameter w and its uncertainty are listed in Cols. 11 and 12.
