Notes
Detector 8 is SEGMENTED after the 2014 anneal!
On March 13, 2015 the rear fast threshold was changed.
15-072-22:05:41 /IDPUTABLE8 OFFSET=REARFASTDAC
15-072-22:05:56 /IDPLOAD VALUE=0x55
- On April 7 2015, the rear fast threshold was changed due to extremely low livetime in the rear segment. It is not clear if this helped; the action will probably be repeated.

15-097-19:57:37 /IDPLOAD VALUE=0x70 ; was 0x65
- On April 9 2015, the rear fast threshold was changed due to low livetime in the rear segment.
