TL;DR: The cosmic ray spectrum is measured using the two air-fluorescence detectors of the High Resolution Fly's Eye observatory operating in monocular mode to fit the spectrum to a model consisting of galactic and extragalactic sources.

TL;DR: In this paper, the authors present a method to cross-check and monitor the mirror pointing by using star light, and evaluate the shape of a point-like object as a function of distance to the mirror axis.
