STS2-C (HAM5) moved to Bier Garten to Huddle with STS2-B

This was moved last week.

Attached are some ASDs and coherence plots.  The reference traces are from a time of 20 to 30 miles winds this morning and the current traces are from an early time in the weekend when things were much quieter.

The Y axis looks good with strong coherence and similar spectra responding to the wind-tilt as expected.  The X axis similarities are okay but not as strong as Y's.  We don't understand the Z axis as the HAM5 unit does not respond to the wind like the ITMY seismometer and the coherence is bad compared to the X and especially the Y.
