Per WP#12646, Fil and I went out to the floor and realigned the ITMX green camera, as Sheila noted it was poorly aligned in alog 84819. (Before we began, Corey transitioned the LVEA to laser hazard per WP#12647).

Before going out to align, I locked the X arm in green only using the camera offsets for the alignment. I offloaded this X arm alignment, so it could be preserved once we moved the camera.

With the X arm still locked, Fil and I connected a computer to the green camera output, which gave us a faster, live view of the camera as we adjusted it. Fil used a Rainbow controller to zoom out very far to reduce our chances of moving the beam too much and losing it. Fil then removed the camera housing cover, and adjusted the nobs on the camera. As he adjusted in the desired direction, I zoomed the camera in slowly, to ensure that we were moving the beam closer to center. We iterated this process several times. The first time Fil went to put the camera cover back on, we noticed that the action of placing the cover bumped the aligment a little bit, so we had to overcorrect in the opposite direction slightly so that the beam stayed centered as Fil replaced the cover. I then tried adjusted the zoom and lens slightly, and decided that the image was well-centered enough to finish the work.

Once we were back in the control room, I updated the camera offsets. I have attached the SDF of these new offsets.
