As a part of  the camera alignment study (alog 18033), I noticed that the ASC loops for green X reacted so slow that it took about several minutes to converge. See the attached screenshot. This is a time series when I turned on the ALS X green ASC loops. I was watching the ALS COMM beatnote strength at the same time as a position-sensitive sensor. I suspected that the camera loop (DOF3) is the one which is so slow, but increasing the gain of this loop told me that the UGF is already close to the 0.5 Hz mechanical resonance (10-sih dB away from instability in gain). Perhaps some kind of cross coupling between the loops exist and may be slowing them down. I am not sure how critical this is in terms of the recycling gain, but if one does not wait for these loops to settle, certainly the alignment will not be repeatable.
