There are two quick tasks we want to do on the way to a full lock, isolate BS ISI ST2, and measure PRCL and MICH gains in DRMI.

Isolated BS ISI stage 2, (WP 5652).   We did this because of the upconversion that Robert saw in DARM when shaking the BS ISI, 24194.  We did this without any problems, then the IFO broke lock durring an epics freeze while locking the OMC, so we didn't get a chance to see if it had an impact on DARM.

I also grabbed some OLG measurements with DRMI locked on 1F, as described in WP5654.  (motivated by alog 24136) 

The PRCL gain isn't very different, the main difference is a boost that is on in DRMI but not PRMI.  The MICH gain is about 10dB high though, resulting in a UGF just above 15 Hz for DRMI and around 5.5 Hz for PRMI.  Maybe we should try lock DRMI with a lower MICH gain and see if it catches better.
