Abstract

We discuss the reconstruction of neutrino flavor ratios at astrophysical sources through the future neutrino-telescope measurements. We demonstrate that the accuracies in the measurements of R = φ ( n_μ)/ (φ(v_e) + f(V_τ)) and S = f(v_e)/f(v _τ) should both be better than 10% in order to distinguish between the pion source and the muon-damped source at the 3 σ level.
