NAME

bfxt - BSU F-X transform (both forward and reverse)

SYNOPSIS

bfxt [ -h | infile1 | iopt | infile2 ]

DESCRIPTION

Basic Seismic Utilities (BSU) takes F-X (frequency,space) transform of X-T (space,time) data. The user may choose to unwrap phase, or leave it wrapped on the forward transform to frequency and space. The reverse transform requires both input files (amplitude and phase as input). The code calls E. A. Robinson’s subroutines (DRUM, NLOGN, POLAR). Fortran 77.

Options

-h

Online help giving details on command line arguments

infile1

Input file name (X-T if forward transform, AMPLITUDES if inverse transform).

iopt

Switch for type of transform desired.

1= forward F-X transform, output phase unwrapped.

2= forward F-X transform, output phase wrapped.

-1= inverse transform (requires two input files, Amp,Phase)
infile2

Only required if iopt=-1, PHASE transform file.

NOTE:
If invoked with no options, will prompt user for input parameters.

EXAMPLE:
bfxt wave.seg 1

The forward F-X transform is computed for file wave.seg, producing both an amplitude and phase output file, phase unwrapped.

bfxt bfxtampl.seg -1 bfxtphaz.seg

The inverse F-X transform is computed from the amplitude and phase spectra.

FILES

bfxtampl.seg

Amplitude-space spectrum (iopt = 1 or 2 only)

bfxtphaz.seg

Phase-space spectrum (iopt = 1 or 2 only)

bfxt.seg

Inverse transform (time, space), (iopt = -1 only)

standard output

produces a progress bar

bfxt.lst

echo check of input parameters.
