.SH DESCRIPTION
.br
\fBpscoupe\fP reads data values from \fIfiles\fP [or standard input] and
generates \fIPostScript\fP code that will plot symbols, lines or polygons on a cross-section.
Focal mechanisms  may be specified and require additional columns of data.
The \fIPostScript\fP code is written to standard output. 
.sp
\fIfiles\fP list one or more file-names. If no files are given, \fBpscoupe\fP
will read standard input.
.sp
A \fInew file\fP is created with the new coordinates (\fBx\fP, \fBy\fP) 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 \fI file\fP  is created with extracted events.
.sp 
.TP
\fB\-J\fP
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 \fBMEASURE_UNIT\fP setting in \.gmtdefaults4, but this can be
overridden on the command line by appending \fBc\fP, \fBi\fP, or \fBm\fP to the scale/width value.
When central meridian is optional, default is center of longitude range on \fB\-R\fP option.
Default standard parallel is the equator.
For map height, max dimension, or min dimension, append \fBh\fP, \fB+\fP, or \fB-\fP to the width,
respectively.
.br
More details can be found in the \fBpsbasemap\fP man pages.

of an existing grid file and the \fB\-R\fP settings (and grid spacing, if applicable) are copied from the grid.

but must be present.
