Despite the difficulties due to the location of the experiment at the center of the scientific payload, efforts have been made to determine BeppoSAX Gamma-Ray Burst Monitor detectors response functions by means of extensive on-ground calibrations, Monte Carlo simulations and in-flight testing. Satisfactory results have been obtained particularly for the two detectors co-aligned with the two Wide Field Cameras (WFC, 1.5-26 keV) on-board the same satellite, allowing nearly unprecedented broad band (1.5-700 keV) spectral analysis of events detected by both experiments.
