Reconstructed direction of the dipole of the UHECR events with E ≥ 8 EeV for each of the 300 computed realizations. The scenarios considered are based on source model A, a 1 nG EGMF, the JF12+Planck GMF model with λc = 200 pc and different hypotheses on the source density, 10−3 Mpc−3 (top-left), 10−4 Mpc−3 (top-right) and 10−5 Mpc−3 (bottom-left) in the mother catalog approach. The large square shows the barycenter of the reconstructed dipole. In the 10−4 Mpc−3 case, the large blue full-triangle shows the dipole direction of the selected realization (see text). Bottom-right: the scenario displayed is based on source model A′, a 1 nG EGMF, the JF12+Planck GMF with λc = 50 pc and an underlying homogeneous and isotropic distribution of sources with a 10−4 Mpc−3 density.
