PSL PMC Beam Alignment Twead and Power Watchdog Reset (FAMIS 10738)

While resetting the PSL power watchdogs, I noticed that the PMC reflected power was getting a little high, up to 11.7W.  I therefore tweaked the beam alignment into the PMC; this was done with the ISS OFF.  Changes summarized below:

I turned the ISS back ON, and noticed the diffracted power was below our 2% minimum (~1.4%), so I adjusted the ISS RefSignal from -2.0V to -1.99V.  This brought the diffracted power back to 2%; this change was accepted in both the safe and observe SDF files.

Both PSL power watchdogs were reset at 18:00 UTC (10:00 PST).  This completes FAMIS 10738.
