TL;DR: High Resolution Fly's Eye's measurement of the flux of ultrahigh energy cosmic rays shows a sharp suppression at an energy of 6 x 10(19) eV, consistent with the expected cutoff energy.

TL;DR: These measurements constrain models in which the galactic-to-extragalactic transition is the cause of the energy spectrum ankle at 4x10(18) eV, and are consistent with a predominantly protonic composition of cosmic rays when interpreted via the Q GSJET01 and QGSJET-II high-energy hadronic interaction models.
