Fig. 9
UHECR and UHE photon-integrated fluxes for a source located at 20 Mpc and different values of the maximum energy: 1019.5, 1020, 1020.5 and 1021 eV. Top: a source spectral index β = 2.0 is considered. Bottom: β = 2.6, the integrated flux is normalized assuming that the source provides three cosmic ray events above 5 × 1019 eV.
