Continuing w/ PR3 move recovery. Still having issues with PRMI.
Ran a Manual Alignment 2-3 times after TJ did one.
- Once again INPUT ALIGN was finicky. There were flashes on the order of 0.5-0.8 for TR_X, but no locks. I tried PR2 yaw moves to try and improve alignment/flashes, but this did not help. I also tried small moves w/ IM4, but that had no effect.
- Quit INPUT ALIGN since it was not working out.
- Continued with other alignment steps (except green arms since they are fine).
- SRC Align continued to not work, so I did an SR2_ALIGN & OFFLOAD and then aligned SRM by hand.
- Then took a look at PRMI, but it was lifeless again (on ndscope) and misaligned on yaw via AS_AIR camera.
- Currently taking INPUT_ALIGN to ACQUIRE_XARM_IR
- Sheila had some checks I could do here: watch AS_AIR at this step to get an idea of how input alignment is misaligned (so would have idea of which way to point PR2)
- Also could double the gain (i.e. from 0.04 to 0.08) for H1:LSC-XARM_GAIN to help Xarm lock (and restore gain after optimizing alignment)
- ......But with Sheila on Teamspeak, she noticed a dark offset which was a bit off. She fixed this by-hand and then TR_X immediately locked. She touched up some of the alignment and then we let ALIGN IFO take over.
- Finally INPUT ALIGN completed successfully!
- Now going to rerun PRC ALIGN, MICH BRIGHT and attempt SRC (if latter doesn't work, will skip).
- Then try PRMI again and check for improvements.
PRC_ALIGN required some PRM aligning-by-hand---it was way off and so PRX would not lock.
Forgot to mention that for the locking attempt before the most recent Manual Alignment, FIND_IR did not look great.
