Notes. Maximum allowed neutrino flux at 250 TeV in units of cm-2 s-1 GeV-1. Numbers were obtained assuming the phenomenological luminosity-mass relations of Sect. 3. All cases refer to B = 1μG; αp = 2 refers to 30% loud clusters, our most optimistic while still realistic case; and the cases of αp = 2.2 and 2.4 refer to 100% loud clusters (see Table 1).
