Please see the Syngine website for a detailed and up‐to‐date explanation of the parameters. A couple are also elaborated upon in the Features section of this article and a full example for requesting vertical‐component data for the IU.ANMO station and the 2002 Denali earthquake is available at http://service.iris.edu/irisws/syngine/1/query?network=IU&station=ANMO&components=Z&eventid=GCMT:M110302J (see Data and Resources). SAC, Seismic Analysis Code; STF, source time function.
