LT lanseis

Uses special filtering based mainly on S-transforms and rotates the recorded seismograms optimally in order to improve the S/N ratio of the arrival of P- and S-waves. The red dashed line is the automatic pick as calculated using the kurtosis criterion (on the filtered by the S-transform denoised seismogram) and the black dotted line is the actual position of the first break arrival.
