Related paper Systematic studies of correlations between different order flow harmonics in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV The centrality dependence of SC($m$,$n$) and NSC($m$,$n$) in $\PbPb$ collisions at $\snn=2.76$ TeV. Results are compared to various AMPT models. Left (right) panels show SC($m$,$n$) (NSC($m$,$n$)).[png] [pdf] [eps]
