- Rear fast counts are high again, so we raised the rear fast threshold by 16 steps, in two sets of 8, on the 2015-01-21 BGS pass starting at ~3:30 PST. The new value is 0x60 (was 0x50). Fast rates as eyeballed from the realtime data were approx 58,000 (pre-adjustment), 12,000 (after 8 steps up), and 1600 (after 16 steps up). Livetime percentages were approx 60%, 90%, and 98%, respectively.

- D6 has been showing some strange peaks in the spectrum. We should keep an eye on this and try changing the slow front threshold to see if that affects it.
