/ Abstract
Pachmarhi Array of ˇ Cerenkov Telescopes(PACT), consisting of a distributed array of 25 telescopes is used to sample the atmospheric ˇ Cerenkov Photon showers. The shower front is fitted to a plane and the direction of arrival of pri- mary particle is obtained. The accuracy in the estimation of the arrival direction of showers has been estimated to be ∼ 0 ◦ .1 using 'split' array method. The angular resolution is expected to be even better when a spherical front is used for direction reconstruction or correction for the curvature o f the front is applied. This is the best angular resolution among a ll the currently operating atmospheric ˇ Cerenkov telescopes in the world.
