Ultrahigh Energy Neutrinos at the Pierre Auger Observatory
Figure 9
Fraction of electron neutrinos of energy 1 EeV and triggering the array (solid grey line) and passing the downward-going analysis cuts in the second column of Table 1 (solid black line) as a function of the slant depth of the interaction above the ground. The dashed line represents the fraction of events passing all cuts except for the cut on the Fisher discriminant (see Section 5.2). The efficiencies are calculated in a full SD array (see text for details).
