Improving the Angular Resolution of the Buckland Park Air Shower Array

Abstract

Air showers initiated by primary cosmic rays and gamma rays produce shower fronts which are curved. However, the arrival directions of air shower events have normally been fitted assuming a planar shower front. We present a technique which takes the average shower front shape into account to assign an improved shower direction after a first analysis assuming a plane front. We then examine the resulting angular resolution of the Buckland Park array.
