<h2>DESCRIPTION</h2>
<p style="margin-left:11%; margin-top: 1em"><b>pscoupe</b>
reads data values from <i>files</i> [or standard input] and
generates <i>PostScript</i> code that will plot symbols,
lines or polygons on a cross-section. Focal mechanisms may
be specified and require additional columns of data. The
<i>PostScript</i> code is written to standard output.</p>
<p style="margin-left:11%; margin-top: 1em"><i>files</i>
list one or more file-names. If no files are given,
<b>pscoupe</b> will read standard input.</p>
<p style="margin-left:11%; margin-top: 1em">A <i>new
file</i> is created with the new coordinates (<b>x</b>,
<b>y</b>) and the mechanism (from lower focal half-sphere
for horizontal plane, to half-sphere behind a vertical
plane). When the plane is not horizontal, - north direction
becomes upwards steepest descent direction of the plane (u)
- east direction becomes strike direction of the plane (s) -
down direction (= north^east) becomes u^s <br>
Axis angles are defined in the same way as in horizontal
plane in the new system. <br>
Moment tensor (initially in r, t, f system that is up,
south, east) is defined in (-u^s, -u, s) system. A
<i>file</i> is created with extracted events.</p>

<p style="margin-left:22%;">Principal axis. <i>scale</i>
adjusts the scaling of the radius of the "beach
ball", which will be proportional to the magnitude. The
<i>scale</i> is the size for magnitude = 5 (that is seismic
scalar moment = 4*10e+23 dynes-cm) in <b><A HREF="gmtdefaults.html#MEASURE_UNIT">MEASURE_UNIT</A></b>
(unless <b>c</b>, <b>i</b>, <b>m</b>, or <b>p</b> is
appended to indicate that the size information is in units
of cm, inches, meters, or points, respectively).
(<b>-T</b><i>0</i> option overlays best double couple
transparently.) Put
<b>−Sy</b><i>scale[/fontsize[/offset</i>[<b>u</b>]]]
to plot the only double couple part of moment tensor. Put
<b>−St</b><i>scale[/fontsize[/offset</i>[<b>u</b>]]]
to plot anisotropic part of moment tensor (zero trace). The
color or shade of the compressive quadrants can be specified
with the <b>−G</b> option. The color or shade of the
extensive quadrants can be specified with the
<b>−E</b> option. Parameters are expected to be in the
