The summary page with all the coherences is available at this address:

I used data from the end of the lock stretch, starting from GPS time 1107840506 and using 600 seconds of data.
The main thing to notice is that DARM is coherent with MICH, PRCL and SRCL over almost all the frequencies, see the first attached plot. This is suspicious, and I'm wondering if there is something wrong with the data I'm using...
There is coherence with EY magnetometers at about 74 Hz, I guess this is the ring heater line.
Yup, this is the right data -- we saw the same coherences using DTT.
There is also coherence with the ISS second loop PDs (the loop was open during this lock).
Yes, I confirm coherence with ISS second loop as well. The shape of the coherence and the projected noise is very similar. So my guess is that the DARM signal was actually limited almost everywhere by intensity noise. But maybe you guys alredy knew that...
