he_relp is the version of the Regional Earthquake Location Program (RELP)
set up for use by the Historical Earthquake Relocation Project (HERP).

To compile he_relp, invoke:

make he_relp

To run he_relp, invoke:

he_relp pickfile

where pickfile is the phase data file (ie: 500720.205639.pf)

For each event, he_relp reads the *.pf file containing phase data and the 
*.af file containing amplitude data and it outputs three files:

500720.205639.sl - detailed solution file

500720.205639.el - concise solution file

500720.205639.ml - magnitude file

Sample he_relp I/O files for the 500720.205639 event are included in this
directory.
