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 article, a method is developed for measuring autocorrelation with asymmetric angular resolution, and it is concluded that HiRes-I observations are consistent with no autocorerelation and that the sensitivity to clustering of the HiResI detector is comparable to that of the reported AGASA data set.
