Dipole amplitude and p-value. Top-left: scatter plot of the dipole amplitude reconstructed for 300 datasets computed for various astrophysical scenarios, based on the baseline volume-limited catalog, source model A and the JF12+Planck GMF with λc = 200 pc in the energy bins 4 ≤ E < 8 EeV and E ≥ 8 EeV. The four scenarios displayed differ by the assumed variance of the EGMF, 10, 3, 1 or 0.1 nG and the Auger ±1σ confidence intervals are shown with shaded areas. Top-right: same as the top-left panel, but the scenarios now differ by the assumed value of λc, 50, 200, 500 and 2000 pc. In all case a 1 nG EGMF is assumed. Bottom-left: scatter plot of the estimated p-values corresponding to the cases displayed on the top-right panel, the p-values found by Auger are shown by a full black marker. Bottom-right: scatter plot of the dipole amplitude reconstructed for 300 datasets for the same astrophysical scenario as on the top-right panel, the two cases shown differ by the assumed GMF model, JF12+Planck or Sun+Planck (in both cases λc = 200 pc).
