Hi Marc,
please could you help us understand why we got such unusual autocorrelation curves?
The attached figure shows the geometry of the array. The sensors are Lennartz 3C 5s and Minishark recorders. The 3Cdata allowed the calculation of good quality spectral curves with a low frequency peak at all seven stations.
What is, in your experience, the reason for the sinusoidal trend of the lower frequency data (we have verified that the response is the same starting from 0.2Hz)?
Best Regards
