NAME

traplt - BSU program generates line-printer plots (time, freq) of a selected trace

SYNOPSIS

traplt [ -h | infile | tmin | tmax | trace# | tzero | ilin ]

DESCRIPTION

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.
