Basic Seismic
Utilities (BSU) plots seismic traces. This program uses
either
the PLPLOT library or GNUPLOT, depending on how it is
compiled. Web sites are
http://plplot.sourceforge.net or http://www.gnuplot.info
Output devices include X-window (interactive only with
gnuplot), Post Script (PS),
Xfig CAD file, JPEG bitmap, and Portable Document Format
(PDF).
Traces may be displayed as simple wiggle, variable area
(peak filled black, white trough), or variable area (peak
filled black, grey
trough). Both PostScript and Xfig output can be scaled to
desired axis lengths
in inches with the xaxis and yaxis parameters. JPEG images
are specified in
100’s of pixels, so xaxis=5 yaxis=6 will produce a 500
x 600 pixel image if compiled
with gnuplot.
C-Language Version.

NOTE:
If invoked with no options, will prompt user for input
parameters (except xaxis
and yaxis).
EXAMPLE:
bplt w001.seg 1 0 1 1 50 0 .1 1 100. 200. 5. 2.5
File w001.seg
traces are plotted. The output will be a PostScript file,
landscape orientation, traces plotted by source-receiver
offset, traces 1 to 50
plotted, traces plotted from 0 to 0.100 seconds, a value of
100 on a trace will
plot one trace spacing, traces clipped at +/- 1 trace,
non-time axis plotted 5
inches long, time axis plotted 2.5 inches long.
