H1-L1 coherence at 74 Hz
We've continued to investigate activity around 74 Hz in order to explain the coherence line between H1 and L1 generated by stochmon.
Attached is a comprehensive set of results from the coherence tool (the full set of results can be found here). The coherence tool plots coherence with the local (H1 or L1) h(t) channel, averaged over a week with 1mHz resolution. The slides attached show the channels showing coherence structure around 74 Hz over the course of O1. You can find relevant plots via a download link in the attached slides.

Has any more digging gone in to investigating my suggested mechanism for coherence at this frequency (see LHO aLOG 24305)? Does this channel list support of refute the claim? Tagging the SEI, SUS, AOS, ISC, and SYS groups again.
