bwin

NAME

bwin - BSU program which applies raised cosine window in time to seismic traces

SYNOPSIS

bwin [ -h | infile | tw1 | tw2 | tw3 | tw4 ]

DESCRIPTION

Basic Seismic Utilities (BSU) applies a window in time. The taper in and taper out is done with a raised cosine. Samples before tw1 and after tw4 are multiplied by zero. Samples from tw1 to tw2 are multiplied by a raised cosine that reaches unity at tw2. Samples from tw3 to tw4 are multiplied by a raised cosine that reaches zero at tw4. Samples from tw2 to tw3 are multiplied by unity.

Options

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

EXAMPLE:
bwin twave.seg 0.1 .12 .4 .42

Data are multiplied by a window which tapers in from 0.1 to .12 seconds, is unity from 0.12 to 0.4 seconds, and then tapers out by 0.42 seconds. Data before 0.1 or after 0.42 seconds are set to zero.

FILES

bwinxxxx.seg

Named according to convention (first 4char bwin, the next 4char are the first 4char of the input file name, suffix .seg)

standard output

produces a progress bar

bwinxxxx.lst

echo check of input parameters
