Abstract
We have measured the cosmic ray spectrum above using the two air-fluorescence detectors of the High Resolution Fly’s Eye observatory operating in monocular mode. We describe the detector, phototube, and atmospheric calibrations, as well as the analysis techniques for the two detectors. We fit the spectrum to a model consisting of galactic and extragalactic sources.
