Every time commissioners improve the sensitivity, I have to run again my brute force coherence. Luckily, it's fast enough now. Here is the sumamry page:

MICH is dominant between 20 and 150 Hz (first plot). PSL periscope peaks are prominent (third plot). Intensity noise is a factor of few below DARM at frequencies above 100 Hz (fourth plot). There are many lines coherent with suspension or environmental signals, too many to list all of them here.

SRCL and PRCL show a broad band coherence basically everywhere (second plot), giving a noise projection a level of few below the DARM signal. This is the usual thing we already saw, and I believe is due to the IMC locking offset, somehow converting frequency noise into intensity noise. Still to be proven though.
