- Control room is at +66 F. Brrrr.
- Alignment of input beam into the IMC was wacky; locked on HOM.
- Re-aligned beam into the PMC first.
- Restarted mxstream for c1sus.
- Power cycled Martian router; all laptops were lost. Now better.
- Aligned launch beam from PSL to get onto the MCWFS better, MC is locking OK now. Moved MC SUS a little to get back to OSEM values from 6 days ago.
- Fixed LOCK_MC screen quad displays to be cooler.
- changed many of the ezcawrite calls in the mcup / mcdown to be 'caput -l' for more robustness. Still need ezcawrite for the binbary calls.
- I didn't touch the mirrors on the MC REFL path, so we can still use that as a reference once the temperature returns to normal; the PSL room temp is down to 20C from 22 C a couple days ago.
- TRX values coming in to the LSC were frozen and the TRY_OUT16 was going to huge values even though camera flashes were reasonable. Tried restarting c1lsc model. No luck.
- Also tried shutdown -r now on c1lsc. No luck. Probably needs a RFM boot.
- Increased the FSS SLOW servo threshold to 9999 counts to avoid it running on some misaligned TEM01 mode locks. Increased the PID's I gain from 0.05 to 0.356 by tuning on some step responses as usual.
- By midnight the control room temperature is back around 71 F.
