MICH and SRCL FF could use a retune. Also, the 15.6 Hz peak that is injecting noise in Kappa_UIM line is due to a misplaced sharp feature in the MICH FF (see 71790)
Unfortunately CHARD_Y is now closer to DARM. This is not a surprise since new filter has higher noise injection. Some of this coherence might be due to HAM1 motion, so maybe it's time to revisit the HAM1 FF to CHARD? Maybe HAM1 is again coupling through CHARD_P, tthat has large coherence with HAM1 motion now.
DHARD_Y is now showing up with some coherence, so we should keep an eye on it
