DESCRIPTION

       pscoupe reads data values from files [or standard input]  and  generates  PostScript  code
       that  will  plot  symbols,  lines  or polygons on a cross-section. Focal mechanisms may be
       specified and require additional columns of  data.  The  PostScript  code  is  written  to
       standard output.

       Unless   is  used,  new  file is created with the new coordinates (x, y) 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 Axis angles are defined in the same way as
       in horizontal plane in the new system.  Moment tensor (initially in r, t, f system that is
       up, south, east) is defined in (-u^s, -u, s) system.

REQUIRED ARGUMENTS

table One or more ASCII (or binary, see -bi[ncols][type]) data table file(s) holding a
number of data columns. If no tables are given then we read from standard input.

-Jparameters (more ...)
Select map projection.

-R[unit]west/east/south/north[/zmin/zmax][r]
west, east, south, and north specify the region of interest, and you may specify
them in decimal degrees or in [+-]dd:mm[:ss.xxx][W|E|S|N] format. Append r if lower
left and upper right map coordinates are given instead of w/e/s/n. The two
shorthands -Rg and -Rd stand for global domain (0/360 and -180/+180 in longitude
respectively, with -90/+90 in latitude). Alternatively for grid creation, give
Rcodelon/lat/nx/ny, where code is a 2-character combination of L, C, R (for left,
center, or right) and T, M, B for top, middle, or bottom. e.g., BL for lower left.
This indicates which point on a rectangular region the lon/lat coordinate refers
to, and the grid dimensions nx and ny with grid spacings via -I is used to create
the corresponding region. Alternatively, specify the name of an existing grid file
and the -R settings (and grid spacing, if applicable) are copied from the grid.
Using -Runit expects projected (Cartesian) coordinates compatible with chosen -J
and we inversely project to determine actual rectangular geographic region. For
perspective view (-p), optionally append /zmin/zmax. In case of perspective view
(-p), a z-range (zmin, zmax) can be appended to indicate the third dimension. This
needs to be done only when using the -Jz option, not when using only the -p option.
In the latter case a perspective view of the plane is plotted, with no third
dimension. If frame is defined from cross-section parameters (see -A this option is
not taken into account, but must be present.

-A selects the cross-section.

-Aalon1/lat1/lon2/lat2/dip/p_width/dmin/dmax[f]
lon and lat are the longitude and latitude of points 1 and 2 limiting the
length of the cross-section. dip is the dip of the plane on which the
cross-section is made. p_width is the width of the cross-section on each
side of a vertical plane or above and under an oblique plane. dmin and dmax
are the distances min and max from horizontal plane, along steepest descent
direction. Add f to get the frame from the cross-section parameters.

-Ablon1/lat1/strike/p_length/dip/p_width/dmin/dmax[f]
lon1 and lat1 are the longitude and latitude of the beginning of the
cross-section. strike is the azimuth of the direction of the cross-section.
p_length is the length along which the cross-section is made. The other
parameters are the same as for -Aa option.

-Acx1/y1/x2/y2/dip/p_width/dmin/dmax[f]
The same as -Aa option with x and y cartesian coordinates.

-Adx1/y1/strike/p_length/dip/p_width/dmin/dmax[f]
The same as -Ab option with x and y cartesian coordinates.

-S selects the meaning of the columns in the data file and the figure to be plotted.

-Sascale[/fontsize[/offset[u]]]
Focal mechanisms in Aki and Richards convention. scale adjusts the scaling
of the radius of the "beach ball", which will be proportional to the
magnitude. The scale is the size for magnitude = 5 in PROJ_LENGTH_UNIT
(unless c, i, or p is appended to indicate that the size information is in
units of cm, inches, meters, or points, respectively). Use the -T 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 -G option. The color or shade of the extensive quadrants
can be specified with the -E option. Parameters are expected to be in the
following columns:

-Scscale

PROJ_LENGTH_UNIT (unless c, i, or p is appended to indicate that the size
information is in units of cm, inches, meters, or points, respectively). Use
the -T option to render the beach ball transparent by drawing only the nodal
planes and the circumference. The color or shade of the compressive

14: text string to appear above the beach ball (default) or under (add
u).

-Spscale[/fontsize[/offset[u]]]

scaling of the radius of the "beach ball", which will be proportional to the
magnitude. The scale is the size for magnitude = 5 (that is seismic scalar
moment = 4E+23 dynes-cm) in PROJ_LENGTH_UNIT (unless c, i, or p is appended
to indicate that the size information is in units of cm, inches, meters, or
