Resumen:
We describe the method devised to reconstruct inclined cosmic-ray air
showers with zenith angles greater than 60° detected with the
surface array of the Pierre Auger Observatory. The measured signals at
the ground level are fitted to muon density distributions predicted with
atmospheric cascade models to obtain the relative shower size as an
overall normalization parameter. The method is evaluated using simulated
showers to test its performance. The energy of the cosmic rays is
calibrated using a sub-sample of events reconstructed with both the
fluorescence and surface array techniques. The reconstruction method
described here provides the basis of complementary analyses including an
independent measurement of the energy spectrum of ultra-high energy
cosmic rays using very inclined events collected by the Pierre Auger
Observatory.
