UHECR energy spectra obtained after propagation in the extragalactic and Galactic media, for source model A assuming the different hypotheses on the source density, 10−3 Mpc−3 (top-left), 10−3.5 Mpc−3 (top-right),10−4 Mpc−3 (bottom-left), 10−5 Mpc−3 (bottom-right), in the mother catalog approach. An EGMF of 1 nG and the JF12+Planck GMF model with λc = 200 pc are assumed in all cases. The simulated sky coverage is that of the Pierre Auger Observatory. The lines show the mean expected fluxes averaged over 300 realizations and the shaded areas cover the range in which 90% of the realizations are found (energy bin by energy bin). The different colors show different groups of nuclear species, as indicated on each plot.
