Fitting the HiRes Spectra and Monocular Composition
Fitting the HiRes Spectra and Monocular Composition
In the first section, we discuss our fits to the latest HiRes monocular spectra. We find that the best fit for the extragalactic component has a spectral index of γ = -2.38±0.04 with a distribution of sources varying with a evolution parameter m = 2.8 ± 0.3. In the second …
