I tried Elenna's FM6 from 80287, this made the PRCL coupled noise worse, see first attached plot.
Then Ryan turned off CAL lines and we retook to preshaping (PRCLFF_excitation_ETMYpum.xml) and PRCL injection (PRCL_excitation.xml) templates. I took the PRCL_excitation.xml injection with the PRCL FF off and increased amplitude from 0.02 to 0.05 to increase coherence over 50Hz. Exported as prclff_coherence/tf.txt, and prcl_coherence/tf_FFoff.txt. All in /opt/rtcds/userapps/release/lsc/h1/scripts/feedforward
Elenna pointed out that I tested the wrong filter, the new one is actual FM7, labeled "new0926". We can test that on Thursday.
The "correct" filter today in FM7 was tested today and still didn't work. Possibly because I still didn't have the correct pre-shaping applied in this fit. I will refit using the nice measurement Camilla took in this alog.
