Abstract
Searches for point astrophysical sources of ultra high energy (UHE) ga mma rays are plagued by large numbers of background events from isotro pic cosmic rays. Some of the methods that have been used to estimate t he expected number of background events coming from the direction of a possible source are found to contain biases. Search techniques that a void this problem are described. There is also a discussion of how to optimize the sensitivity of a search to emission from a point source.
