Notes
After the 2014 anneal, detector 4 is UNSEGMENTED.
- On May 21 starting at 19:24 UTC we raised up the Slow threshold for the Front segment.
15-141-19:24:10 start idib_chg_thrshld (4, FRONT, SLOW, 0x68) --> Was 0x60 15-141-19:24:22 /IDPUDUMPTABL TABLE=DIBTBL4 15-141-19:24:22 /IDPUTABLE4 OFFSET=FRONTSLOWDAC 15-141-19:24:31 /IDPLOAD VALUE=0x68
- Raised front fast threshold due to elevated counts. This change reduced counts and increased livetime
2015-152-17:00:18 /IDPUTABLE4 OFFSET=FRONTFASTDAC 2015-152-17:00:31 /IDPLOAD VALUE=0x60 ; was 0x50
- On 2015 July 7, D4 front fast threshold was raised due to decreased livetime.
2015-188-18:48:17 /IDPUTABLE4 OFFSET=FRONTFASTDAC 2015-188-18:48:34 /IDPLOAD VALUE=0x70 ; was 0x60
