...-processing method is proposed in order to reduce such errors in warping-based interpretation. The requirement of the method, however, is the location of event peaks or troughs, which are not readily available in practice. To make the method more practical, simple integration of traces followed by detrending...

... and S phases of the reference events are picked on the first peaks or troughs, providing picks that are less influenced by the signal-to-noise ratio than onset picking. Initial picks are then obtained for the event to be processed; if picks already exist, these are used; if at least one pick exists...
