Sensitivity and energy resolution estimates of the TACTIC gamma-ray telescope - Inputs from simulation studies (II)

Abstract

The response of the recently-commissioned TACTIC imaging Cerenkov telescope to atmospheric Cerenkov pulses produced by cosmid gamma-ray and hadron-initiated extensive air-showers has been studied through Monte Carlo simulations, using the CORSIKA code (Capdeville et al., 1992). Preliminary results are presented on the likely performance of 3 different imaging camera sizes : 2.8 degree x 2.8 degree, 4.7 degree x 4.7 degree and 5.9 degree x 5.9 degree, with regard to event calorimetry and characterization.
