POX / POY calibration |

...maybe the opto-mechanical CARM plant is changing as a function of the CARM offset...
Quote: |
Even assuming 50% error in the calibration factors, it's hard to explain the swing of TRX/TRY when the CARM offset is brought to zero.
- The increase in (admittedly in-loop) CARM noise as the offset is reduced still seems to me to be correlated with the buildup of IR power in the arm cavities.
