[Keita, Gerardo, Jenne, Cheryl]
With the new input alignment from after the vent, we checked the PRM's parking spot and have found the misaligned location that puts the beam on the steering mirror above the viewport above HAM2. Keita made some small adjustments on that steering mirror to center the beam on the beam dump.
This was WP 7305. It turns out there is no insert for a lexan cover, but Gerardo had (from a previous time doing this) a thick piece of plexiglass that was cut to size to fit over the viewport while these checks and adjustments were made. The plexiglass was removed, and the cover reinstalled.
