Calculation of the gamma-ray line sensitivity of the BATSE large area detectors on GRO

The gamma‐ray line sensitivity of the BATSE detectors depends primarily upon the characteristics of the detectors’ response and the nature of the backgrounds observed by the instruments. Using the example of the detectability of prompt annihilation radiation from nearby novae, the detector response characteristics and data analysis tools relevant to gamma‐ray line and continuum sensitivity determination will be presented. Sensitivities to gamma‐ray lines at various energies will be presented.
