BruCo coherence scan

https://ldas-jobs.ligo-wa.caltech.edu/~gabriele.vajente/brucos/lho_1345273218_modulated/

A scan of all coherences with GDS-CALIB_STRAIN during a lock from August 23, just below 100 Mpc, hopefully useful for noise hunting.

There's a lot of coherence with MICH / PRCL / SRCL even at higher frequency (a few hundred Hz). Also coherence on some structures with the septum accelerometer

At low frequency there's coherence with OMC control signals: not clear to me if that's a real noise source or if it's DARM leaking into OMC signals.
