-
Locked SRY by misaligning PRM and ITMX.
-
Used ASAIR_A_RF45_Q with the whitening gain of 18 dB and two whitening stages engaged.
-
Copied LSC-PRCL filters to LSC-SRCL filters.
-
Copied PRM and PR2 locking filters over to SRM and SR2 respectively.
-
LSC_SRCL_GAIN = 300 to lock the carrier with a UGF of about 5 Hz.
-
Put a notch in SRM because we tended to ring up a vertical mode of SRM at 27.46 Hz. This is partly why the UGF is so low.
-
Still in the process of checking the cross-over and so on.
