Attenuators:
Both D1 and D7 livetimes had continued to degrade since we last changed the attenuator deinsertion settings. Livetime values are now flipping between 97.25% and 97.65% and only rarely jumping a level up from that. Attenuator deinsertion levels at the beginning of this tohban week were 98.04% for the thin and 98.43% for the thick, so if either attenuator were to come in it would not come out until commanded to. Therefore, a change in deinsertion threshold was requested. The A3 out threshold was change from 1.57% to 2.75% deadtime and the A1 out threshold was changed from 1.96 to 2.75% deadtime. The changes were made today, July 24, at 2015-204-17:44:08 UT. The last attenuator motion (A1 to A0) was July 9, 2015.
