- Detector 4 has been unsegmented since the 2012 anneal. The entire detector volume is read out through the front segment electronics, so rates look higher for G4 (and also G2) than for the other detectors.
- 6 November 2012: The front fast and slow thresholds on detector 4 were optimized during 2 passes. The front slow threshold was reduced significantly, down to the nominal value used by segmented detectors, without seeing a large increase in noise. The front fast threshold was lowered a little as well, but not by nearly as much.
G4 Front Slow 0x70 to 0x0C.
G4 Front Fast 0x60 to 0x50.
