- Energy assignment
- GlueX: We have a total of 102 microscope channels covering the energy range from 8.2 - 9.2 GeV for a 12 GeV beam. (The energy numbers need to be scaled for other electron beam energies).
- CPP: We only have 96 microscope channels (last bundle of 6 does not fit), covering the energy range of 4.5 - 6.0 GeV for a 11.57 GeV beam. I assume that the software will retain 102 channels but the last channels should never show hits.
- The hodoscope counter numbers in the array closest to the focal plane (x=-8 cm) are 222 (E=5.95 GeV) and 246 (E=4.52 GeV).
- Scaled energy rage in CCDB entry for microscope.
- Scaled energy range in CCDB entry for hodoscope.
