We did offline wiener filtering on 3rd August (Elog entry) using only Guralps' channels X and Y.
Here we report the Power spectrum of the 3 seismometers (Guralp1, Guralp2, STS1) during that time.
and also the coherence between the data from different channels of the 3 seismometers.
We see that the STS is less correlated with the two Guralps. We think it is due to the wrong alignment of the STS with the interferometer's axes.
We are going to align the STS and move the seismometers closer to the stacks of the X arm.
