obspy.signal.trigger¶
Various routines related to triggering/picking
Module implementing the Recursive STA/LTA. Two versions, a fast ctypes one and a bit slower python one. Furthermore, the classic and delayed STA/LTA, the carlSTATrig and the zDetect are implemented. Also includes picking routines, routines for evaluation and visualization of characteristic functions and a coincidence triggering routine.
