Cheryl and I swtiched to REFL WFS at about 1:34 UTC, and have been locked this way for about an hour without any problems so far.  The secondary microseism is around 0.4 to 0.5 um/second, velocities where we previously had trouble switching to REFL WFS.  You can see in the attached striptool that the transition did make the AS90 build ups a little less stable.  

After this was locked for about a half hour, I made some SRCL injections because of the higher SRCL coherence with this new alignment. It seems like we can do better for the noise around 80-100 Hz by using split FF for now, I've put in the gains of -1.1 for the low frequency filter and -1.3 for the high frequency filter.  (see attached screenshot)  These settings are in the guardain now.  

We closed the beam diverters without incident and are ready to go back to observe.
