DESCRIPTION
pspolar reads data values from files [or standard input] and
generates PostScript code that will plot stations on focal
mechanisms on a map. The PostScript code is written to
standard output.
ARGUMENTS
files List one or more file-names. If no files are given,
pspolar will read standard input.
-J Selects the map projection. Scale is cm/degree, 1:xxxxx.
or width in cm (upper case modifier).
See psbasemap manpages for details.
-R west, east, south, and north specify the Region of
interest. To specify your boundaries in degrees and
minutes, use the dd:mm format.
-Dlongitude/latitude Maps the bubble at given longitude and
latitude point.
-Msize Sets the size of the beach ball to plot polarities
in.
Size is in inch (unless c, i, m, or p is appended).
-S<symbol type>sizeSelects symbol type and symbol size .
Size is in inch (unless c, i, m, or p is appended).
Choose symbol type between
st(a)r, (c)ircle, (d)iamond, (h)exagon, (i)nvtriangle
(p)oint, (s)quare, (t)riangle, (x)cross
OPTIONS
No space between the option flag and the associated argu-
ments.
-B Sets map boundary tickmark intervals. See psbasemap for
details.
-C Offsets focal mechanisms to the latitude and longitude
specified in the last two columns of the input file.
-Efill Selects filling of symbols for stations in extensive
quadrants. Set the shade (0-255) or color (r/g/b) [Default
is 250/250/250]. If Efill is the same as Ffill, use -e to
outline.
-e[<pen attributes>] Outline symbols in extensive quadrants.
Default pen attributes is W pen attributes.
-Ffill Sets background color of the beach ball. Default is
no fill.
-f[<pen attributes>] Outline the beach ball. Default pen
attributes is W pen attributes.
-Gfill Selects filling of symbols for stations in compres-
sional quadrants. Set the shade (0-255) or color (r/g/b)
[Default is 0/0/0].
-g[<pen attributes>] Outline symbols in compressional qua-
drants. Default pen attributes is W pen attributes.
-H[n] Input file(s) has n Header record(s). Number of header
records can be changed by editing your .gmtdefaults file. If
used, GMT-SYSTEM default is 1 header record.
-h
Use special format derived from HYPO71 output
-K Means more PostScript code will be appended later.
[Default terminates the plot system]
-N Does NOT skip symbols that fall outside map border
[Default plots points inside border only].
-O Selects Overlay plot mode. [Default initializes a new
plot system]
-P Selects Portrait plotting mode. [Default is Landscape]
-shalf-
size/[V[<v_width/h_length/h_width/shape>]][G<r/g/b>][L]
Plots S polarity azimuth.
S polarity is in last column. It may be a vector (V option)
or a segment. Give half-size,v_width,h_length,h_width in
inch (unless c, i, m, or p is appended). [L] option is for
outline.
-Tangle/form/justify/fontsize in points
To write station code. Default is 0.0/0/5/12.
-t<pen attributes>
To write station code. Default attributes is W attributes.
-U Draws Unix System time stamp on plot. Append c to plot
the command line or a text string of your choice.
-V Verbose. Reports the name of the current file being
plotted, as well as number of records, and any scaling
information.
-W Set current pen attributes
[Defaults: width = 1, color = 0/0/0, texture = solid].
-X -Y Shift origin of plot by (x-shift,y-shift) inches
[Default is (1,1) for new plots, (0,0) for overlays].
-: Toggles between (longitude,latitude) and
(latitude,longitude) input/output. [Default is
(longitude,latitude)]
-c Specifies the number of plot copies. [Default is 1]
Parameters are expected to be in the following columns
1,2,3,4
station_code, azimuth, take-off angle, polarity
polarity :
- compression can be c,C,u,U,+
- rarefaction can be d,D,r,R,-
- not defined is anything else
