Detector issues
On October 8, several detector fast thresholds were raised in order to bring down fast rates and thus free up livetime. Prior to these changes, D5 and D6 front livetimes were at ~30% and ~20% respectively, and livetimes were extremely low for D1,3,7 rear. As the changes were made on a BGS pass, the D5 front fast rates fell from 131k to 2100 and the D6 front fast rates fell from 100k to 9000. The livetimes rose accordingly, so the changes were successful. The effects of the rear threshold changes still need to be assessed. Commanding times are below.
