supef

seismic software,very useful

SUPEF - Wiener predictive error filtering
supef <stdin >stdout  [optional parameters]
Required parameters:
	dt is a mandatory getpar if not set in header
Optional parameters:
     minlag=dt	first lag of prediction filter (sec)
     maxlag=trace/20	last lag of prediction filter (sec) [note below]
     pnoise=0.001	relative additive noise level
     mincorr=tmin	start of autocorrelation window (sec)
     maxcorr=tmax	end of autocorrelation window (sec)
     showwiener=0	=1 to show Wiener filter on each trace
     showspiker=0	=1 to show spike decon filter on each trace
Trace header fields accessed: ns, dt
Trace header fields modified: none
Note: The precise maxlag formula is (tmax-tmin)/20.
Caveat: Times are measured relative to the first trace sample.
	To get the Wiener filters into an ascii file:
	... | supef ... showwiener=1 2>file | ...   (sh or ksh)
	(... | supef ... showwiener=1 | ...) >&file  (csh)
