made it to DC readout - now in NLN
issues getting here:
- REFL WFS centering not coming on in Inital alignment for PRC and SRC, so in both cases those didn't complete until engaged by hand (guardian?)
- alignment
- POPA OFFSETS - Evan looks at these - not sure they're OK but in the end they seem to work
- ASC - Evan toggled PRC1_P on and off (3 seconds each) to save the lock and also allow PRC1 P to converge
- POPA sum got noisy in ENGAGE SOFT LOOPS until I engaged the CHARD offset of 0.1 by hand in Engage Soft Loops, then the signal improved
- I set the ramp to 120 seconds, and at 120 seconds there's a kick that can be seen on CSOFT_P
- PI mode 2 rang up - easily damped
- PI mode 26 rang up and did a bouncing thing until I lowered the gain by half from -5000 to -2500, and then tuned the phase
