PSL PMC Maintenance (WP 6444)

Remotely from the control room, I tweaked the beam alignment into the PMC; this was done with the ISS OFF.  The power transmitted by the PMC increased to ~66.3W, and the power reflected decreased to ~13.8W.  With the ISS back ON the PMC is transmitting ~63.3W and reflecting ~13.8W.

Also in the WP, the PSL ODC bit 12 (PMC Transmission Limit) was already set to 50W, so no change was made by me today.

While doing this, I reset the power watchdogs for the 35W FE laser and the HPO (FAMIS task 3634).

This closes LHO WP 6444.
