Deflection angle distribution for Fe nuclei of energy 2.5 × 10²⁰ eV propagating through the large‐scale GMF (without including a B_z component). As in Fig. 1, the UHECR positions are distributed in different shades of gray according to their deflection angles as a result of their passage through the GMF. Panel a depicts the arrival directions of Fe nuclei at the Galactic halo border (before deflection by the GMF), and panel b depicts the particle arrival directions at the detector (after deflection by the GMF). Note that the observed UHE events of Akeno, Fly's Eye, and Yakutsk (marked with symbols) do not reveal strong deflections from their original positions.
