suband

seismic software,very useful

SUBAND - apply bandpass filter with sine-squared taper
suband <stdin >stdout [optional parameters]
Required parameters:
	if dt is not set in header, then dt is mandatory
Optional parameters: (nyquist calculated internally)
	f1 = 0.10*(nyquist)	left  low  corner frequency (Hz)
	f2 = 0.15*(nyquist)	left  high corner frequency (Hz)
	f3 = 0.45*(nyquist)	right low  corner frequency (Hz)
	f4 = 0.50*(nyquist)	right high corner frequency (Hz)
	dt = (from header)	time sampling rate (sec)
The filter is applied in frequency domain.
Example:
	suband <data f1=10 f2=12.5 f3=40 f4=50 | ...
