Yesterday, Travis hoofed it down the x-beam manifold from inside of BSC3 to the ITMx OPLEV viewport and mapped the red beams heading toward the receiver.  Only the ITMx-HR main beam and some small ghosts were exiting the viewport, the other main beams were trapped by the manifold spool piece.  Attached is the map.  It looks like the CPx-HR and the ITMx-AR surface beams are close together, as they should be - measured to be ~1.06 mRad away from each other in yaw, and far less in pitch.  (The CP pointing tolerance is ~1.4mRad so this is "within" spec.)  This is good news and means that the back reflections from the CP which go back down towards the input arm should be ~appropriately dumping on baffles when it's all put back together.  We'll try to check during upcoming alignment exercises.

We confirmed that the arrow on the CPx is on the +y side of the optic.
