PCAL End X Tx Module maintenance.

Rick and I cleaned the optics out here at End X.
Noted a drop in MAX Diffracted Power between M5 and the Wedged Beam Splitter from 1.1W to 1.08 W.
This may be due to the laser being turned off and not thermalized.

We would like to come back to End X and adjust the AOM alignment and we are leaving PCAL in a LASER SAFE status, LASER OFF and Key out.
