Kolmogorov‐Smirnov probability, as a function of γ, that the ﹩z^{j}=( L^{j}_{i}/ L_{i}) ^{-\gamma }﹩ are uniformly distributed; ﹩L_{i}﹩ is the limiting ﹩L_{\mathrm{X}\,}﹩ to which cluster i has been observed, ﹩L^{j}_{i}﹩ is the ﹩L_{\mathrm{X}\,}﹩ of source j in cluster i, and γ is the index of the luminosity function ﹩dN\propto L^{-\gamma }_{\mathrm{X}\,}\, d\mathrm{log}\,L_{\mathrm{X}\,}﹩.
