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.
