" Optional parameters:							\n"
" 									\n"
"      minlag=dt	first lag of prediction filter (sec)		\n"
" 									\n"
"      maxlag=trace/20	last lag of prediction filter (sec) [note below]\n"

"      showwiener=0	=1 to show Wiener filter on each trace		\n"

" Trace header fields accessed: ns, dt					\n"
" Trace header fields modified: none					\n"
" 									\n"
" Note: The precise maxlag formula is (tmax-tmin)/20.			\n"
" Caveat: Times are measured relative to the first trace sample.	\n"
