A comparison of the measured Earth-arrival directions of all UHECRs with energies above 56 EeV detected by PAO and AGASA (blue, green, and red open circles with radius 3.5° as in Fig. 1) with the estimated outside-the-Galaxy arrival directions of the same UHECR (crosses) within the BS-S model for UHECR compositions of protons (red), He (green), oxygen (blue), aluminum (yellow), and calcium and iron (black). The first three compositions of the same UHECR are connected with blue lines, while the heavier compositions are not connected to avoid plot overcrowding. Other symbols and names in the figure are the same as in Fig. 1.
