Check how the STSs look with a big Earthquake--HAM2 Y no good

My usual image of ASD and coherence between the three corner station STS2s.

Great coherence pretty much on everyone from 1 hz down to .002hz except HAM2 Y.  HAM2 X is better but still not as good as Z or the other instruments.  With this signal size, there is no excuse for poor coherence.  I'm going to move the HAM2 sensor back to the BierGarten for one final check.
