I installed POP_SM4 and POP_SM5 in the ITMX chamber in the nominal positions. This must have affected the ITMX Oplev because I could see that one of the ITMX oplev beam was going through POP_SM5. It needs to be changed in order to follow the original plan. However, since POP_SM5 is a 1064 line mirror, it is transparent to the opleve beam, so maybe we can just use the ITMX oplev in the current fashion.

Next steps:

• Get flashing back on the XARM.
• Try to get the correct phase angle in POX11 so that we can lock XARM with IR too.
• Inspect ITMX Oplev. The quadrant sum is low so maybe it needs adjustment in the in-ar table.
• Check if ITMX oplev path needs to be adjusted inside the chamber.
