Had a lockloss this morning. Once h1 was back up to NLN, took this opportunity to lower the gain of ITMy Mode5 from -0.04 (nominal) to -0.02. Attaching another trend of the ITMy 5+6 modes for the last 3.5 days. (The cursor on the top plot is when Tony worked on Mode5 & the cursor on the plot below it is when Rahul made changes to address rung up Mode 6.
The camera/access system computer froze up. Access system came back fine, but the camera app can not connect to the server. Richard had me reboot the Bosch box in the Server Room, but still can't connect.
Here is a look at the OMC DCPD over the weekend. It looks as though the damping down of the violins is turning around and begining to ring up again. At 1955utc (1255pmPT) I took the ITMy Mode-5 gain from -0.02 down to -0.01 to see if this helps & will touch base with Rahul...and then go make lunch.
I have switched off damping for IY 03, 04, 07 and 08 and will then attempt to damp IY 05/06 in some time with reduced gains. This worked well all day yesterday, so will give it another try.
Edit - OK, the above strategy didn't work, IY 05/06 are still rising, I will need to change the phase and look for a new setting.
