Ultrahigh Energy Neutrinos at the Pierre Auger Observatory

T3 trigger (open dots) and identification (closed dots, cuts as in Table 1) efficiency in the Earth-skimming analysis, as a function of the height above ground of the shower at 10 km from the decay point . The efficiency is shown for Monte Carlo showers induced by s with energy (clockwise from (a)) 0.1, 1, 10 and 100 EeV. The efficiencies are calculated in a full SD array (see text for details).
