We've asked Tony to try locking the IFO with SR3 and SR2 in these very different positions. With these optic positions, we don't want the AS_C offsets in place that we used to get locked yesterday. So, I have now accepted in safe.snap for the ASC model that the AS_C offsets are off (but I've left the numerical values).
If we're unable to lock, then the plan is to ask Tony to revert SR2 and SR3 and turn back on those offsets. Since the offset switches are part of SDF revert, to turn them on the plan should be to go Sitemap -> ASC -> Overview -> AS_C (bottom left) -> Turn on the offsets and save the diff in SDF.
First attachment is my saving the safe.snap file with the offsets off. Second attachment is where the offset buttons are.
We've gotten as far as PRMI locked (with arms held off resonance with ALS, as usual), and at some point as soon as PRMI ASC comes on MICH Yaw gets a 2.2 Hz wiggle.
EDIT to add that a thing to try could be to turn off the ASC during PRMI (set lines 737 and 738 of ISC_DRMI.py to False). If we have similar problems in DRMI ASC, also set lines 1026-1031 to False. Save, then reload ISC_DRMI guardian.
EDIT EDIT: I just set line 737 to False. It may be beneficial to tune up the alignment by hand.
EDIT EDIT EDIT: We're still getting wobbles, even though the guardian had turned off the MICH ASC, and I had by-hand turned off the PRC1 ASC.
EDIT EDIT EDIT EDIT : I also set PRC1 to False on line 738 and loaded. I have to go now though, so good luck Tony!
We had an almost 30 hour lock, but probably we want PRMI ASC to work again now that we're relocking. RyanS and I have just set lines 737 and 738 back to True to enable PRMI ASC.
