From the Table 1.15.1 it can be seen that the expected ratios of CR photons to CR particles are of the order of ~ 10-3 in the energy range 1016-1017 eV if primary photons are injected within the circle of less than 2 rs around the Sun. However, in order to detect one shower initiated in the atmosphere by photon with energy 1016 eV from the direction of the Sun, the statistics of showers of the order of ~ 108 is needed because of small solid angle of the Sun.
