Public Functions

templates_max_similarity Compares all event templates in the streams_templates list of streams against the given stream around the time of the suspected event.
xcorr Cross correlation of tr1 and tr2 in the time domain using window_len.
xcorr_3c Calculates the cross correlation on each of the specified components separately, stacks them together and estimates the maximum and shift of maximum on the stack.
xcorr_max Return shift and value of maximum xcorr function :type fct: ndarray :param fct: xcorr function e.g.
xcorr_pick_correction Calculate the correction for the differential pick time determined by cross correlation of the waveforms in narrow windows around the pick times.
