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.
