RyanC, Jenne, RyanS
The ground and wind finally let us lock which let me get to and fix the following small software issue to recover Observing.
16:26 UTC I removed an errant 'H1:' (good eye RyanS) in a ezca call in LOWNOISE_ESD_ETMX, and commented out the newest lines Jenne added at her suggestion and reloaded ISC_LOCK. Here are some the quads L3 lock filters right after LOWNOISE_ESD_ETMY finishes. I was then able to get back up to NLN after spending ~10 minutes in OMC_WHITENING
From LOWNOISE_ESD_ETMX's main method I commented out:
# if ezca['SUS-ETMY_L3_DRIVEALIGN_L2L_GAIN'] != 1:# ezca.get_LIGOFilter('SUS-ETMY_L3_DRIVEALIGN_L2L').only_on('INPUT','OUTPUT','DECIMATION')# ezca['SUS-ETMY_L3_DRIVEALIGN_L2L_GAIN'] = 1# ezca['H1:SUS-ETMY_L3_LOCK_OUTSW_L'] = 0 (Deleted H1:, the real issue here)In [1]: ezca.get_LIGOFilter('LSC-MICHFF').ramp_gain(0, ramp_time=3, wait=False)
H1:LSC-MICHFF_GAIN => 0
In [2]: ezca.get_LIGOFilter('LSC-SRCLFF1').ramp_gain(0, ramp_time=3, wait=False)
H1:LSC-SRCLFF1_GAIN => 0
In [4]: ezca.get_LIGOFilter('LSC-PRCLFF').ramp_gain(0, ramp_time=3, wait=False)
H1:LSC-PRCLFF_GAIN => 0
I then ran the commented out lines, excluding the if line waited a little bit then returned the FF gains to 1. There was a SQZ SDF diff I accepted.
I've uncommented out this block with the fixed typo but I forgot to reload ISC_LOCK, the typo fix has been svned.
17:24 UTC Observing
