Abstract

We present the reconstruction of neutrino flavor ratios at astrophysical sources. For distinguishing the pion source and the muon-damped source to the 3$Ï$ level, the neutrino flux ratios, $R\equivÏ(Î½_Î¼)/(Ï(Î½_e)+Ï(Î½_Ï))$ and $S\equivÏ(Î½_e)/Ï(Î½_Ï)$, need to be measured in accuracies better than 10%.
