We present the reconstruction of neutrino flavor ratios at astrophysical sources. For distinguishing the pion source and the muon-damped source to the 3 σ level, the neutrino flux ratios, R ≡ φ{symbol} (νμ) / (φ{symbol} (νe) + φ{symbol} (ντ)) and S ≡ φ{symbol} (νe) / (φ{symbol} (ντ)), need to be measured in accuracies better than 10%.
