This may require a manual move of the picomotor and pushing flex part manually against the picomotor, to make sure that it is actually controlling the mirror tilt.//

-The next part is to verify with the WL source, repeating the same steps, but this time using the CLIMB server and GUI and look at the spots in NIRO. Make sure that no covers are left on the fold mirrors. When looking at the spots with NIRO GUI tab: Pixel Area, when adjusting, you just watch only that spot which was left open in the laser procedure, see the diagram of spots in NIRO on the printed diagram.

 ==== Example of How to Recover the Alignment of IRBC23: ====
-Diagnosing Problem: Following the steps above using the green laser on the CLIMB table and the white light source with the pixel area of the NIRO detector. When looking at the light from Beam 3 only, light appeared on pixel 123A and 123B, but not on 23. Light from Beam 2 only appeared in 23, but not in 123A and 123B. Comparing with the CLIMB layout diagram, this indicated a problem with IRBC23.

 To recover IRBC23, use the green laser first
