Friday morning, the STS2-B (new) instrument was put under the igloo.  Attached areASDs, coherences and unit to unit TFs with original references--references from the old unit, within its igloo, legs still on vinyl.  The current traces are from 0130pdt 27 April.  The seismic environment was boring at that time.

Comparing these traces with the orignal (references) and the plots from Friday AM in aLog 18046:

The ITMY (STS2-B) Z DOF ASD looks much more like the other seismometers (STS2-A & C/HAM2 & HAM5) although the coherence with the A & C units has decreased in the 40-80 mHz region.

The X & Y DOFs don't show anything readily synthesized.  The unit to unit TFs show similar results as previous (aLog 18046) except the X DOF unity TF is now back up above 0.1 up from .07Hz on Friday.

The main thing I see is the improvement in the Z DOF (2nd attachment.)  All the units look very similar now in Z.

Maybe the long wavelength signals are predominantly vertical and the horizontals are a greater mix including short wavelengths...
