Betsy, Hugh
There are some channels which we have identified with SDF that change between lock stretches and should therefore be not monitored. So far, Hugh and I have set the foolwing to not be monitored:
- SR3 CAGE SERVO OFFSET -SR3_M2_TEST_P_OFFSET)
- BSC ISI CPS SETPOINTS_NOW
- IMC PZT P/Y OFFSETS
- LSC PSL-POWER_SCALE_OFFSET
- ALS CAMERA SERVO SETTINGS (ALS_CAM)
- PSL-ISS_REFSIGNAL and PSL-ISS_SECONDLOOP_REF_SIGNAL_ANA
We have not set the alignment sliders to be NOT MONitored so be prepared to set those tonight as needed:
ALL SUS OPTICALIGN P/Y OFFSETS
Again, if you run into problems with red alarms on any SDF screen that is blocking you from hitting the Intent bit, please 1) check with your commissioners to clear any temporary changes and then 2) set the outstanding channels to NOT MON and we will audit them tomorrow when we continue on this work.
In prep for going to Observe this evening, I NOT MONed a few channels. All of these should stay NOT MONed.
In addition, the new epoch of SDF caught something, that we may not have caught without it. See alog 21389 for details, but the LSC-PRCL gain was not correct. It was reverted by hand, and then the guardian bug was fixed. We used to have this channel "NOT MON"ed by SDF (since it is changed by guardian), which is likely why we haven't noticed this before.
