Energy spectra of TeV sources measured with the Durham Mark 6 telescope

/ Abstract
A programme of detailed simulations of the response of the Durham Mark 6 atmospheric Cherenkov telescope is in progress. The effective collecting area for triggering by gamma-ray showers after application of selection criteria is derived as a function of energy. An initial result from the larger events in the 1996 and 1997 observations of the BL Lac PKS 2155–304 is that the time averaged flux above 1.5 TeV was (6:7 2:2) 10 8 m 2 s .
