<h2>DESCRIPTION

</h2>
<p style="margin-left:11%; margin-top: 1em"><b>psmeca</b>
reads data values from <i>files</i> [or standard input] and
generates <i>PostScript</i> code that will plot focal
mechanisms on a map. Most options are the same as for
<b><A HREF="psxy.html">psxy</A></b>. The <i>PostScript</i> code is written to
standard output.</p>

<p>Selects the map projection. Scale is UNIT/degree,
1:xxxxx, or width in UNIT (upper case modifier). UNIT is cm,
inch, or m, depending on the <b><A HREF="gmtdefaults.html#MEASURE_UNIT">MEASURE_UNIT</A></b> setting in
.gmtdefaults4, but this can be overridden on the command
line by appending <b>c</b>, <b>i</b>, or <b>m</b> to the
scale/width value. When central meridian is optional,
default is center of longitude range on <b>−R</b>
option. Default standard parallel is the equator. For map
height, max dimension, or min dimension, append <b>h</b>,
<b>+</b>, or <b>-</b> to the width, respectively.</p></td></tr>

<p style="margin-left:22%;">Focal mechanisms in Aki and
Richards convention. <i>scale</i> adjusts the scaling of the
radius of the "beach ball", which will be
proportional to the magnitude. Scale is the size for
magnitude = 5 in inch (unless <b>c</b>, <b>i</b>, <b>m</b>,
or <b>p</b> is appended). Use the <b>−T</b> option to
render the beach ball transparent by drawing only the nodal
planes and the circumference. 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 following columns: <br>

<b>p</b> is appended). (<b>−T</b><i>0</i> option
overlays best double couple transparently.) Use

will be proportional to the magnitude. Scale is the size for
magnitude = 5 in inch (unless <b>c</b>, <b>i</b>, <b>m</b>,
or <b>p</b> is appended). 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 following columns: <br>
longitude, latitude of event (<b>−:</b> option
interchanges order) <br>
depth of event in kilometers <br>
strike, dip of plane 1 <br>
strike of plane 2 <br>
must be -1/+1 for a normal/inverse fault <br>
magnitude <br>
longitude, latitude at which to place beach ball. Entries in

these</p>
<p style="margin-left:35%;">columns are necessary with the
<b>−C</b> option. Using (0,0) in columns 9 and 10 will
plot the beach ball at the longitude, latitude given in
columns 1 and 2. The <b>−:</b> option will interchange
the order of columns (1,2) and (9,10).</p>
<p style="margin-left:22%;">Text string to appear above the

<p style="margin-left:11%;"><b>−Sx|y|t</b><i>scale[/fontsize[/offset</i>[<b>u</b>]]]</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.
Scale is the size for magnitude = 5 (that is seismic scalar
moment = 4*10e+23 dynes-cm) in inch (unless <b>c</b>,
<b>i</b>, <b>m</b>, or <b>p</b> is appended).
(<b>−T</b><i>0</i> option overlays best double couple
transparently.) Use <b>−Sx</b> to plot standard
Harvard CMT. Use <b>−Sy</b> to plot only the double
couple part of moment tensor. Use <b>−St</b> to plot
zero trace moment tensor. 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 following columns: <br>
longitude, latitude of event (<b>−:</b> option
interchanges order) <br>
depth of event in kilometers <br>
value (in 10*exponent dynes-cm), azimuth, plunge of T, N, P
<br>
axis. <br>
exponent <br>
longitude, latitude at which to place beach ball. Entries in
<br>
these</p>
<p style="margin-left:43%;">columns are necessary with the
<b>−C</b> option. Using (0,0) in columns 14 and 15
will plot the beach ball at the longitude, latitude given in
columns 1 and 2. The <b>−:</b> option will interchange
the order of columns (1,2) and (14,15).</p>
