Xarm is aligned for both IR and green. 

Here is a photo of the beam paths of the PSL beat setup.  I want to make sure that the X-green BBPD sees a nice beam from both the PSL and the Xarm, without disturbing the currently working Y setup.  I keep getting confused with all the beamsplitters, especially the green PBSes, which operate at ~56deg, not 45deg, so I made a diagram.
