PERL PROGRAM NAME: supswigp - PostScript Bit-mapped WIGgle plot of a segy data set AUTHOR: Juan Lorenzo (Perl module only) DATE: DESCRIPTION: Version:
supswigp - PostScript Bit-mapped WIGgle plot of a segy data set supswigp <stdin [optional parameters] > Optional parameters: key=(keyword) if set, the values of x2 are set from header field specified by keyword n2=tr.ntr or number of traces in the data set (ntr is an alias for n2) d1=tr.d1 or tr.dt/10^6 sampling interval in the fast dimension =.004 for seismic (if not set) =1.0 for nonseismic (if not set) d2=tr.d2 sampling interval in the slow dimension =1.0 (if not set) f1=tr.f1 or tr.delrt/10^3 or 0.0 first sample in the fast dimension f2=tr.f2 or tr.tracr or tr.tracl first sample in the slow dimension =1.0 for seismic (if not set) =d2 for nonseismic (if not set) style=seismic normal (axis 1 horizontal, axis 2 vertical) or vsp (same as normal with axis 2 reversed) Note: vsp requires use of a keyword verbose=0 =1 to print some useful information tmpdir= if non-empty, use the value as a directory path prefix for storing temporary files; else if the the CWP_TMPDIR environment variable is set use its value for the path; else use tmpfile() Note that for seismic time domain data, the "fast dimension" is time and the "slow dimension" is usually trace number or range. Also note that "foreign" data tapes may have something unexpected in the d2,f2 fields, use segyclean to clear these if you can afford the processing time or use d2= f2= to override the header values if not. If key=keyword is set, then the values of x2 are taken from the header field represented by the keyword (for example key=offset, will show traces in true offset). This permit unequally spaced traces to be plotted. Type sukeyword -o to see the complete list of SU keywords. This program is really just a wrapper for the plotting program: pswigb See the pswigb selfdoc for the remaining parameters. Trace header fields accessed: ns, ntr, tracr, tracl, delrt, trid, dt, d1, d2, f1, f2, keyword (if set) Credits: CWP: Dave Hale and Zhiming Li (pswigb, etc.) Jack Cohen and John Stockwell (supswigp, etc.) Delphi: Alexander Koek, added support for irregularly spaced traces Modified by Brian Zook, Southwest Research Institute, to honor scale factors, added vsp style Notes: When the number of traces isn't known, we need to count the traces for pswigb. You can make this value "known" either by getparring n2 or by having the ntr field set in the trace header. A getparred value takes precedence over the value in the trace header. When we must compute ntr, we don't allocate a 2-d array, but just content ourselves with copying trace by trace from the data "file" to the pipe into the plotting program. Although we could use tr.data, we allocate a trace buffer for code clarity.
supswigp inherits all the properties of PSWIGP
PSWIGP - PostScript WIGgle-trace plot of f(x1,x2) via Polygons Best for few traces. Use PSWIGB (Bitmap version) for many traces.

Thus the result is device-dependent, put generally looks the best for seismic traces. The curve file is an ascii file with the points specified as x1 x2 pairs, one pair to a line. A "vector" of curve files and curve colors may be specified as curvefile=file1,file2,etc. and similarly curvecolor=color1,color2,etc, and the number | ...of pairs of values in each file as npair=npair1,npair2,... .
