traplt - BSU program generates line-printer plots (time, freq) of a selected trace
traplt [ -h | infile | tmin | tmax | trace# | tzero | ilin ]
Basic Seismic Utilities (BSU) lists sample values next to a line-printer style plot, displaying waveform with "*" symbols. A namelist of the sample amplitudes follows the plot, suitable for use with the filtering program bftr. After the namelist, a line-printer spectral plot is displayed, showing amplitude and phase. The user may plot amplitude on a linear or decibel scale. Fortran 77.
Options
|
-h |
Online help giving details on command line arguments | ||
|
infile |
Input file name | ||
|
tmin |
The start time for the data to be displayed (beginning of aperture). | ||
|
tmax |
The end time for the data to be displayed (end of aperture). | ||
|
trace# |
The trace number to be displayed (can select only one trace). | ||
|
tzero |
Time zero reference for phase plot. A delayed arrival will have a highly wrapped phase plot. Setting tzero to the arrival time of a wavelet permits better viewing of the phase. | ||
|
ilin |
Switch to select the type of plot (linear or decibel) |
0=decibel (logarithmic)
1=linear (normalized on maximum value)
NOTE:
If invoked with no options, will prompt user for input
parameters.
EXAMPLE:
traplt wave.seg 0. .10 10 .05 1
Trace 10 of file wave.seg is plotted from 0 to 0.1 seconds. The time reference for the phase plot is set at .05 seconds, and the amplitudes are plot on a linear scale.
standard output
produces a progress bar
traplt.lst
echo check of input parameters and line-printer plots.
