| Abstract | We report a measurement of the cosmic ray energy spectrum obt ained using the inclined events detected with the Pierre Auger Observatory. Showers ith zenith angles between 60 ◦ and 80◦ recorded in the period between 1 January 2004 and 28 February 2007 are analysed. Showers are first reconstructed in arrival direction and then fitted to densit y maps of the muon numbers obtained from 10 eV simulated proton showers for different arrival directio ns, in order to obtain the core position and an overall normalisation factor N19 which is used as an energy estimator. The parameter N19 is shown to be correlated with the shower energy measured with the fluo rescence technique for a sub-sample of good quality hybrid showers. This correlation, measured wi th hybrid events, is then used to determine the energy of all the showers. |
