This surface plot is the same as the previous one, with a little more data than I had previously.
This time around, I also include the "BLRMS" plots for this data. The first one takes each residual and normalizes it by the DARM_CTRL signal at that time, separates the spectra into bands, and integrates underneath the spectra within that band. The second one is the raw DARM_CTRL signal's spectra at each time, and integrates under the spectra for each band, and the third BLRMS plot does the same thing for the residuals. Unfortunately, these plots don't have the same handy black stripe during time which I don't analyze that the spectrogram utilizes.
From the second BLRMS plot we can see that the large red splotch in the spectrogram is due to higher noise in the DARM spectrum, and that (by looking at the Ratio BLRMS plot) the Wiener filter still does a pretty good job during this time. I expect that for later times when the seismic (or something) event is gone, the Wiener filter will continue performing almost as well as it had been initially.
Again, once the script finishes applying the filter to the many ten minute chunks (the huge time drain is the data fetching, so this shouldn't be a limiting factor for using Wiener filters online), I'll post a final plot.
