Abstract

Pachmarhi Array of \v{C}erenkov Telescopes(PACT), consisting of a distributed array of 25 telescopes is used to sample the atmospheric \v{C}erenkov Photon showers. The shower front is fitted to a plane and the direction of arrival of primary particle is obtained. The accuracy in the estimation of the arrival direction of showers has been estimated to be $\sim 0^{\circ}.1~$ 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 of the front is applied. This is the best angular resolution among all the currently operating atmospheric \v{C}erenkov telescopes in the world.
