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.

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.
