Abstract

We have searched the Whipple 1988-89 canonical Crab Nebula database for evidence of a possible geomagnetic field effect on the sensitivity of the atmospheric Cherenkov imaging technique. At the present sensitivity of the imaging technique, the selection of gamma-ray-like events on the basis of image characteristics appears to be unaffected by the transverse field strength. We are unable to detect any broadening of shower images or any increase in integrated light content.
