Jim and crew completed the installation of the shield panels today. They also adjusted the compression of the upper-right (when viewed from the ETM) flexure gap to ~0.220".
Everything seems to be installed as designed.

Began assessing the centering of the Pcal beams on the input and output apertures using targets mounted to the Pcal window flanges on the A1 adapter. We plan to continue this work in the morning, going inside the vacuum envelope to assess centering on the Pcal periscope relay mirrors.
We plan to install the Pcal target on the ETM suspension cage for this work.
