The last two columns of Table 7 show the estimated time to get a detection for each trigger condition, first for the case of only having as a source the neutrino flux given by the extrapolation of the measurement done by IceCube [12] and also for the case of including GZK neutrinos from [9].

The addition of the flux [[PHI].sub.A]A + [[PHI].sub.C] to the extrapolation of the IC flux is motivated by their approximation to GZK neutrinos produced by interactions with the EBL and CMB [9].
Thanks to the GZK cutoff, UHECRs cannot be the result of quasars, gamma-ray bursts, or anything else at cosmological distances.
Awareness of the GZK cutoff also made it hard to believe in any measurement above 5 x [10.sup.19] eV.
This was so far beyond the GZK cutoff that researchers first believed it had to be a technical glitch.
Their source had to be within 100 million light-years of Earth--close enough to preempt the GZK cutoff.
Since 1993 AGASA has recorded a few dozen particles beyond the GZK cutoff, including just 11 events with energies above [10.sup.20] eV.
