We measured the PRC1 ASC loops, and adjusted the suspension compensation such that we could increase the UGF to about 0.3 Hz for each. This included sending the ASC control signals to M3 of the PRM, in addition to M1.  There's room to increase the gain, but we want to maintain our heirarchy with the PRC2 loops of 2Hz ugf from last night.  See screenshots for new loop TFs.

We tried to modify the way the MICH ASC loops come on, so that we're less rough with the turn-on, but were unsuccessful.  The idea was to have FM2 (0.03:0) off but FM3 (:0.03) on so that we don't have a pure integrator.  We planned to turn the input on with zero gain, then ramp up the gain.  Once the loop is on, we were going to engage FM2 to cancel FM3's pole and give us a pure integrator.  This kept kicking us out of lock though, so we've backed out these changes, and just put a sleep in after the MICH loops come on, before any other loops come on.  We did however make the MICH yaw loop use the -20dB FM1 initially and then ramp it off, in the same way that the pitch loop does. We also increased FM1's ramp time from 2 sec to 4 sec.  This seemed to help enough that we're leaving it for now, and may come back to it in the future.

The "msboost"s in the CHARD loops are causing loop oscillations now, so we've commented them out of the guardian.  We'll have to revisit why this is happening, and fix it (refl wfs phasing due to preloading?).  This may need to be addressed before we can power up.

The environment is starting to get fussy (high winds and moderate useism), so we're going to leave things as-is for now.  Locking should all be the same as usual through DC readout.  We make no warranty for power-up, since we haven't had a chance to try it.

Plan: Get to Part3 or DC readout, measure phasing of refl wfs by shaking mcl and checking that signals all in I phase (hopefully).  Should be okay with the new preloading, since it's all fine with regular hot IFO.  Fix if needed.  Then try powering up!
