Angular power spectrum of our simulations (assuming a full-sky exposure) for the source model A, 2MRS-based catalogs with source density 1.4 × 10−3 Mpc−3 in the volume-limited approach and various hypothesis on the galactic and extragalactic magnetic fields. The lines show the average values obtained over 300 realizations, the (red) shaded area show the range in which 99% of isotropic UHECR simulations are found with the same statistics as our datasets. Top panel: predictions for various values of the EGMF intensity and no GMF. Middle panel: same cases but now assuming the JF12+Planck GMF model with λc = 200 pc. Bottom panel: case of a 1 nG EGMF for various assumptions regarding the GMF coherence length. Central and bottom panels: the predictions (for  = 1 and 2) are compared with the estimate of the full sky UHECR power spectrum obtained after a joint analysis of Auger and TA data (above 8.86 or 10 EeV according to Auger’s or TA’s energy scales respectively, adapted from Biteau et al. 2019).
