7.1 The hypocenter program, HYP

The hypocenter program is a modified version of HYPOCENTER (Lienert et al., 1986; Lienert, 1991; Lienert and Havskov, 1995). The main modifications are that it can accept more phases, locate teleseismic events and use input in Nordic format directly from the database. A detailed manual (earlier version, hypocent.pdf) and some of the later changes
(hypocent_latest.pdf) is given in INF directory. The input parameter file with station coordinates, model etc. is STATION0.HYP, see later. The station file has all the stations currently registered at ISC so the user migh want to use a smaller set of stations.
