In 86481, Elenna proposed using a new FF fit as the bruco showed SRCL coherence, this has improved the low frequency SRCL noise, but moved the bump at 200Hz to 100Hz, overal a small improvement, see plot attached. Saved in ISC_LOCK and safe and observe sdfs.
I doubled the amplitude of the injection from 0.04 to 0.08, ran the template and saved as /lsc/h1/scripts/feedforward/SRCL_excitation.xml while FM5 was on, so that in the future we can try to fit a separate >100Hz filter as Elenna suggests in 86481. I didn't measure the pre-shaping as expect we recently have that.
In preparation to create a high frequency SRCL FF based on this data, I copied the SRCLFF1 FM10 highpass into FM10 of SRCLFF2 (not to be confused with a different, older "highpass" in FM1 of SRCLFF2).
