Below is my outline of locking attempts so far this morning, with any changes I made in Guardian or otherwise in bold:
- Plan to start w/ initial alignment then allow ISC_LOCK to go up to 'RESONANCE' if possible
- Sheila messages saying CARM_TO_ANALOG won't work; changed ISC_LOCK line 2826 from 2 to 8
- Alignment goes without issue, just needed some SRM adjustment
- Lockloss early in 'RESONANCE', maybe actually something at end of CARM_TO_REFL like Ibrahim found last night
- DHARD control signals got very glitchy
- Relocked - lockloss while waiting in CARM_TO_REFL after it finished; definitely end of this state (matrix loading?) is the issue
- While relocking, lockloss in DHARD_WFS, seems like alignment was just bad
- Added SRC loops back into DRMI ASC since they should work after Elenna's dark offset updates
- They do
- Relocked - holding in CARM_5_PICOMETERS while stepping CHARD P and Y to try and increase LSC-REFL
- Not seeing much appreciable improvement
- Reverted Sheila's REFLAIR phase changes from yesterday
- Tried CARM_TO_REFL again; lockloss
- SDF_REVERT reverts my phase reversion
- Relocked - held in CARM_5_PIVOMETERS to measure TR CARM transfer function
- Gain looks too high compared to Feb 2023 reference (screenshot 1), changed LSC_TR_REFLAIR9_CARM_TO_REF gain in lscparams from -0.8 to -0.46 (might undo this later)
- Remeasured (screenshot 2)
- Tried CARM_TO_REFL again with new gain; lockloss
