The method is derived empirically and utilizes several features of gamma-ray-induced air showers which determine, to a precision of 0.12°, the arrival direction of photons on an event-by-event basis. Data from the Whipple Observatory's 10 m gamma-ray telescope are utilized to test selection methods based on source location. The results compare these selection methods with traditional techniques and three different camera fields of view. The method will be discussed in the context of a search for a gamma-ray signal from a point source located anywhere within the field of view and from regions of extended emission.","claims":[{"public_id":"cl_dbac8844f164b1a7a7d4404d568128ad","status":"active","text":"An empirically derived atmospheric Cherenkov imaging method reconstructs the unique arrival direction
