Subject Classification: | 04. Solid Earth::04.06. Seismology::04.06.06. Surveys, measurements, and monitoring | Abstract: | Although the Earthworm project started with the initial mission of replacing the old real time picker by Rex Allen, as developed by Jim Ellis [Allen, 1978; Allen, 1982; USGS et al., 2010], that picker is still in use in many networks. The name of the procedure that implements the Allen’s algorithm is pick_ew. Despite its long-lived use, configuring this picker still seems not so immediate and easy. We discuss here a few simple rules to define some of the numerous (18) parameters of pick_ew, interpreting their physical meaning. |
