This morning, while the MC was unlocked, I zeroed the offsets of WFS_A and WFS_B. I wanted to check if they were responsible for the IMC angular offsets I added recently.
The answer seems to be negative. I had tom retuned the IMC DOF offsets, but the optimal values are still not zero:
DOF | Pitch | Yaw |
---|---|---|
1 | 30 | -15 |
2 | -20 | -7 |
3 | -1.5e-3 | -2e-3 |
