Notes on global shear wave splitting analysis
... Typically, teleseismic S arrivals have a dominant frequency of about 0.1 Hz, so it is usually best to set the upper limit of a band-pass filter to about 0.3 Hz. The lower limit should not be higher than about 0.05 Hz, but the lower the better. This is because a band-limited signal will look much lik ...
