EndX Pcal alignment check

TravisS, RickS

Yesterday afternoon, we transitioned Xend to Laser Hazard, energized the Pcal laser, checked the beam centering on the Pcal Receiver Module power sensor, then transitioned back to Laser Safe.

The beams are well-centered on the power sensor aperture (see attached photo), indicating that the beams are still where we want them on the ETM surface.
