The Arm is locked, as off 03:24:00 UTC (20:24h local time).
The various controls are in the state listed below.
Channel of interest is 'H2:ALS-Y_ARM_LONG_IN1_DQ' and has units of nm (and is sampled at 16k).
HPI State:
All running fine. The cavity feedback (off load) at low frequencies to HPI ETMY, with a UGF of ~1 mHz. ETMY_ISCINF_LONG has a a 250k nm limit on the output (I got an effective limit of 200k nm on the output of the signal ISC sends into the RFM).
ISI State:
Stage 1, (ITM/ETM) X/Y 250mHz blend other at 750mHz blend
Stage 2: (ITM/ETM) XY 100mHz other 750mHz blend.
Quad Sate:
ETM: M0 damping on, L1 L/P damping only, L2 no damping (watch dog off), L3 no damping
ITM: M0 damping on, L1 L/P damping only, L2 no damping (watch dog off), L3 no damping (watch dog off)
Attached is an initial spectrum .... the frequency noise has dropped nicely! (due to 3791)
