I engaged the boost filter that Gabreile desgined 77865, the attached screenshot shows that this reduced the DHARD P rms by amost half. 

With this boost engaged I ran the same SRCL excitiation as in 77648 at 18:45:59- 18:55:00 UTC 5/24/24. 

Next week we can add this DHARD P boost into the guardian at LOWNOISE_ASC. 

After this I quickly adjusted the SRCL FF gain to reduce the coupling to DARM at 30Hz a little, screenshot attached.
