PMC Output Since NPRO Crystal Temperature Tuning

Attached is a roughly 19 hour trend, going back to relocking the PMC/ISS/FSS after yesterday's NPRO crystal temperature tuning.  As can be seen, there were no excursions in PMC Refl above 18 W, and no sudden drops in the ISS diffracted power % or sudden ISS unlocks, a clear change from the last several days.  We will continue to monitor this, but so far it looks like the new NPRO is much happier with this new crystal temperature.
