<!--EOF-->
Wiener filter. The first call produces the original periodogram on stdout (or
in <font color=blue><em>file</em><tt>_amp</tt></font> with the <font
color=blue><tt> -o </tt></font> option). This may then be edited to provide the
desired periodogram. The second call uses <em>file</em> and the output of
<font color=blue><tt>wiener1</tt></font> to generate a filtered sequence. The
final result is written to stdout, or <font
color=blue><em>file</em><tt>_wc</tt></font> with the <font color=blue><tt> -O
</tt></font> option). The option setting of <font color=blue><tt> -o
</tt></font> should be the same for both calls. Internally, the series is
padded with zeroes in order to get a FFT-able number of points. A warning is
issued if applicable.
