Print this reportComment to IMC input alignment script (9368)The ASC part in the IMC guardian (ASC_RFON) was modified to do only input PZT2 loop [*].
Now you can do either
1. "LSC_LOCKED" + input alignment script (see the main post)
2. "IMC_LOCKED" only
Note that the ASC loop done by "IMC LOCKED" doesn't do any offloading at this moment, while the script does. DoF2 P and Y loops are both optimized so to have UGF 0.1 Hz (see the attached OLTs).
As long as I tried for this few hours both methods work stably. Please let me know any feedback if you notice any.
[*] it's not the complete DoF WFSing, but it sufficiently aligns the input beam w.r.t. the IMC axis.
