Preliminary Analysis of Monocular HiRes Prototype Data

The HiRes prototype detector with 14 mirrors has been operational for more than two years. Some air showers are observed in coincidence with other detectors (CASA, MIA, FE2, HiRes2). However, here we examine the larger data set which includes showers observed by the HiRes prototype alone. We describe the analysis techniques of shower reconstruction for the monocular data. Preliminary distributions are reported. We have also done a pilot study search
