For this purpose we have assumed three different hypotheses for the neutrino production model, characterised by the flavour fluxes at production \\phi_e^0:\\phi_\\mu^0:\\phi_\\tau^0 = 1:2:0, 0:1:0, and 1:0:0, and studied the theoretical and experimental expectations for the muon-neutrino flux at Earth, \\phi_\\mu, and for the flavour ratios at Earth, R = \\phi_\\mu/\\phi_e and S = \\phi_\\tau/\\phi_\\mu.
