Posting a measurement from last week. This data was collected at GPS time 1058659398 (23 July 2013, 5:03 pm PDT).

The data shows the coherence between all 6 ETMY ISIINF channels from 0.1 Hz to 10 Hz. The ISI was damped, with no isolation at this time. These are the witness channels of ISI STG2 in the SUS model that later get projected into the suspension point witness channels. The matrix of data can be read as the coherence from the channel name across the top of the figure to the channel name along the left side of the figure. Note that the data consists of a symmetric matrix, e.g. RX to Y is the same as Y to RX. 

The data shows the most off-diagonal coherence between X and RY, Y and RX. RZ also has some moderate coherence to everything except Z.
