摘要：

A cost-effective methodology for operating the 349-pixel Cerenkov light imaging camera of the imaging clement of the TACTIC gamma -ray telescope array at stable single-counts rate and safe anode current values has successfully been tried out despite variations in the light of the night sky experienced by these pixels from time to time. Important details of this unconventional scheme are discussed and reference is made to the methods evolved for in situ absolute and relative gain calibrations of the camera pixels, which air particularly required for this mode of operation.
