It is my pleasure to announce that the first lock of PR2 flipped PRMI was succeeded.
POP looks very nice. TEM00 and not wobbling.
We need more I/Q phase and gain/filter adjustment and characterization soon.
Some more details:
MICH error signal: AS55_Q_ERR (using POP55 PD; phase rotation angle 70 deg)
PRCL error signal: REFL11_I_ERR (phase rotation angle 80 deg)
MICH feedback: BS (MICH_GAIN = -60)
PRCL feedback: PRM (PRCL_GAIN = -0.5)
