I also removed the explicit range for the PSD color scaling as it wasn't great in some circumstances.

Did you gain any insights already?

So far mainly a few airframe specifics, but maybe more generally seeing how valuable even a single well placed notch can be in many cases rather than the conservative low pass cutoff.
