SYNOPSIS
SEISMIC UNIX NOTES SUPSGRAPH - PostScript GRAPH plot of a segy data set
supsgraph <stdin [optional parameters] >
Optional parameters:
style=seismic seismic is default here, =normal is alternate
(see psgraph selfdoc for style definitions)
nplot is the number of traces (ntr is an acceptable alias for nplot)
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)
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 over-ride the header values if
not.
See the psgraph selfdoc for the remaining parameters.
On NeXT: supsgraph < infile [optional parameters] | open

Notes:
When the number of traces isn't known, we need to count
the traces for pswigp. You can make this value "known"
either by getparring nplot 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.User's notes (Juan Lorenzo)
