NAME

bxcr - BSU program which peforms cross-correlation between two data sets

SYNOPSIS

bxcr [ -h | infile1 | infile2 | t1 | t2 | tlagmx ]

DESCRIPTION

Basic Seismic Utilities (BSU) cross correlates two different data sets (or the same data set with itself, autocorrelation). The zero lag point is set at the middle of the output data set. The aperture is established independently from the number of lags.

Options

-h

Online help giving details on command line arguments

infile1

Input file 1 name

infile2

Input file 2 name (can be same as infile 1)

t1

Start time of aperture

t2

End time of aperture

tlagmx

Maximum shift (in time, seconds). This is symetrical about zero lag.

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

EXAMPLE:
bxcr wav1.seg wav2.seg 0. .10 .05

File wav1.seg is cross correlated with wav2.seg. Only samples from 0 to 0.1 seconds are included in the correlation, and the maximum shift is .05 seconds.

FILES

bxcrxxxx.seg

Output, correlation data set. Named according to convention (first 4char bxcr, the next 4char are the first 4char of the input file name, suffix .seg)

standard output

produces a progress bar

bxcrxxxx.lst

echo check of input parameters
