Description
We discuss the reconstruction of neutrino flavor ratios at astrophysical sources from future neutrino-telescope measurements, given the
knowledge of neutrino mixing angles obtained from terrestrial
experiments. With a statistical analysis, we demonstrate that the pion source and the muon-damped source can be distinguished at the $3\, \sigma$ level provided the accuracies on measuring $R\equiv\phi (\nu_{\mu})/\left(\phi (\nu_{e})+\phi
(\nu_{\tau})\right)$ and $S\equiv\phi (\nu_e)/\phi
(\nu_{\tau})$ can both reach $10\%$. On the other hand, the above two sources are very difficult to distinguish by merely measuring $R$ alone. We also discuss the effect of leptonic CP phase on such a flavor-ratio reconstruction.
