H1 Locking: TCSy Laser Recovery

Since we had a cold ITMy for almost 3hrs (I did not hear the verbal alarm warning about the TCSy laser during Maintenance.), we are waiting for ITMy to thermally equalize....we're getting there, but there continues to be some drift.  

To help speed up recovery, Keita changed the Requested Power for the TCSy Laser from

While locking, PRMI flashes looked fairly ugly.  When we did lock, POP18/90 had a slow thermal drift.  

Eventually locked DRMI (but had a lockloss).  Now that we may be equalizing thermally, it might be useful to run a new alignment (I ran one when the ITMy was cold!).  But Travis is going to  give it a go without running an alignment for a first attempt.
