Based on fluorescence observations in coincidence with at least one surface detector we derive a spectrum for energies above 1018 eV. We also update the previously published energy spectrum obtained with the surface detector array. The two spectra are combined addressing the systematic uncertainties and, in particular, the influence of the energy resolution on the spectral shape. The spectrum can be described by a broken power law E−γ with index γ=3.3 below the ankle which is measured at log10(Eankle/eV)=18.6. Above the ankle the spectrum is described by a power law with index 2.6 followed by a flux suppression, above about log10(E/eV)=19.5, detected with high statistical significance.Submitted by Bruna Lessa (lessbruna@gmail.com) on 2012-05-14T20:20:09Z No. of bitstreams: 1 (20)1-s2.0-S0370269310001875-main.pdf: 501159 bytes, checksum: 2ef6e672f42baaf0b492895ab50b1402 (MD5)Made available in DSpace on 2012-05-14T20:20:09Z (GMT).
