Caption: Figure 9.

Top panel: the normalized distribution of the extragalactic amplitudes of the identified solutions from the top panel of Figure 5 for the individual models of the UF23 model of the GMF. Middle panel: possible extragalactic directions of a dipole, compatible at the 1σ (dashed lines) and 2σ (solid lines) levels with the Auger measurement for the eight individual UF23 models of the GMF, shown in Galactic coordinates, using the mass composition obtained for model SIBYLL 2.3d + ΔXmax. Bottom panel: possible extragalactic directions of a dipole at the 2σ level for the UF23 base model of the GMF and three different coherence lengths, shown in Galactic coordinates, using the mass composition obtained for the model SIBYLL 2.3d + ΔXmax.
