Detector issues
On January 5 at 14:57 UTC, we changed thresholds on the front fast and front slow values for G5.
Threshold | Front Fast | Front Slow |
Initial | 0x60 | 0x80 |
D5 has largely segmented over the past week. The next tohban should try to lower the front threshold.
The other detectors are stable, 2 and 4 are unsegmented.
Light leak in D2 front, D9 rear and D5 rear.
