It was decided that the recent changes of the IMs and the PRs might have put us in a bad alignment ( alog76366 and some control room and matter most conversations) . We reverted those to two days ago, scope trend, and then we decided to try to pico the HAM3 pop pico - labeled as ALS/POP beam steering HAM1, motor 8. This didn't make any positive changes in the beatnotes and arm powers together, so we brought them back to their starting positions and decided it was bes to to to ISCT1 to help match our IFO alignment, bring our DIFF beatnote back up, and we could fix some clipping that we've known about on the ALSY path to the PD and camera (alog76287).
Before going on table I ran a green initial alignment, input align, and mich bright. The BS circled in pink on the layout attached was translated to reduce the clipping on that optic. The downstream BSs within the light blue circle then needed to be adjusted to maximize the diff beatnote.
