Notes
- There was a large spike in D1 on September 2 at ~07:16 UT.
This caused the shutters to engage and the other detectors to spike as well
- 2014 May 17:
- G1 rear fast threshold from 0x45 to 0x50
- A short and negligible problem arose when it was intended to command detector 4, but used the command for G1, the "/IDPUTABLE[X]" command. The error was caught, and the "bad" threshold setting was only in place for about 3 minutes. Entire commanding sequence is below.
