The fit v2^2(eta_1,eta_2)=v2(eta_1) x v2(eta_2) is not found to
describe the data successfully for (Delta eta cut)<1.2, as
demonstrated by the strong (Delta eta cut) dependence of extracted
non-flow ratio. The non-flow ratio values for (Delta eta cut)<1.2 are
not listed since these values are based on a wrong assumption that
non-flow correlations are not present beyond (Delta eta)>(Delta eta
cut) with (Delta eta cut)<1.2.
