Notes. This table summarizes the statistics of the matches between UHECRs detected by the Pierre Auger Observatory and selected areas around Cen A and and around the concentration of extended radiogalaxies. Columns are: (1) GMF model; (2) fraction of the total (1350) outside-the-galaxy arrival directions that fall within a distance of 20° of Cen A and its extended radio lobes in the case of proton UHECRs; (3) number of UHECRs (of the total of 27) that have at least one of their fifty outside-the-galaxy arrival directions within 20° of Cen A and its extended radio lobes in the case of proton UHECRs; (4) fraction of the total (1350) outside-the-galaxy arrival directions that fall within the “radiogalaxy box” with limits in Galactic coordinates 240° ≥ l ≤ 360° and −10° ≥ b ≤ 70°; (5) number of UHECRs (of the total of 27) that have at least one of their fifty outside-the-galaxy arrival directions within the “radiogalaxy box” described above; (6 to 21) as in Cols. 2 to 5 but for heavier compositions as labelled.
