New SRCL FF in place

Jennie, Ryan S, Camilla

After Jennie's 78629 measurements, we fit the SRCL FF (not time for MICH). Possible we might add noise at 300Hz but this is FF looks overall better.

Old SRCLFF was FM2 with gain 1.18 (didn't account fort this is code but should have changed this to 1 for best iterative fitting). New FF is FM4 gain 1.18. Plot attached. SDF saved and ISC_LOCK edited and loaded.

This new FF does a good job of making the SRCL coherence low (see first attachment).
