<h2>DESCRIPTION</h2>
<p style="margin-left:11%; margin-top: 1em"><b>pspolar</b>
reads data values from <i>files</i> [or standard input] and
generates <i>PostScript</i> code that will plot stations on
focal mechanisms on a map. The <i>PostScript</i> code is
written to standard output.</p>
<p style="margin-left:11%; margin-top: 1em">Parameters are
expected to be in the following columns <b><br>
1,2,3,4</b></p>
<p style="margin-left:22%;">station_code, azimuth, take-off
angle, polarity</p>
<p style="margin-left:22%; margin-top: 1em">polarity: <br>
- compression can be c,C,u,U,+ <br>
- rarefaction can be d,D,r,R,- <br>
- not defined is anything else</p>
