    • Events triggering only by the bismuth germanate (BGO) crystal of the GRS are accepted gamma-ray events; events triggering both by the BGO and anti-coincidence shield (ACS) are rejected and are due to energetic charged particles and gamma-rays that deposit a fraction of their energy in the ACS (5)
