bwin - BSU program which applies raised cosine window in time to seismic traces
bwin [ -h | infile | tw1 | tw2 | tw3 | tw4 ]
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.

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.
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
