  A method of a search for local sources of superhigh energy gamma rays is
described in the paper.It is shown that the method is more effective then the
usually used method extracting excess from total intensity if gamma ray burst
durations are short.Using the suggested method,the information detected with
the Baksan installation ``Carpet'' during 1992-1996 years was analyzed.An
excess of event numbers was found at the confidence level of 6.5$\sigma$ in the
direction to Mrk 501.
