Ultrahigh Energy Neutrinos at the Pierre Auger Observatory

Figure 7

Distribution of the value of the Fisher polynomial ( , see text for details) for events with number of selected stations . Data in the training period (see Table 2) describe the nucleonic background, while Monte Carlo simulated downward-going neutrinos correspond to the signal. The vertical lines indicate needed to expect 1 event in the labeled periods of time (full SD array).
