TL;DR: The magnetic rigidity of the cosmic ray was reliably determined by highly precise measurement of the circular track in a uniform solenoidal magnetic field of 1 T in 1998 as discussed by the authors, and the cosmic-ray proton and helium spectra were determined within overall uncertainties of ±5% for protons and ±10% for helium nuclei including statistical and systematic errors.

TL;DR: In this paper, anisotropy in the arrival directions of cosmic rays with energies above 10$^{17}$eV was studied using data from the Akeno 20 km$^2$ array and the AGASA, using a total of about 117,000 showers observed during 11 years.
