Attached are ASD comparing the Old (troublesome) STS2-B and the newly repaired STS2 temporarily in place in the beer garden. The current traces are from ~0130pdt--looks like a quiet time based on the PEM traces.
When I compare these to the plots (calibrations in meters) in 18007 from Wednesday AM, I observe the following:
Strong coherences are moving to lower frequencies in all DOFs.
Unity transfer function for X DOF too is moving down in frequency. The Y & Z TFs look pretty similar.
Maybe this means these signals are getting more stable. However, the Z signal of the Old & New STS2-B still don't look like the A & C units, is this an indication of the vinyl difference?
