[daip] more Archive strangeness

[Joseph Lazio]

John,

Continuing the puzzle, I was able to download the data.  Below are two
items.  The first is an extract from FILLM (TST version at the AOC),
in which FILLM claims that there are two spectral windows, 1.37 and
1.435 GHz (which is what I vaguely recall from the original
observations).   The second shows the IMHEADER from one of the
resulting files produced by FILLM in which only one IF is listed, that
at 1.37 GHz.  Other than the obvious adverbs (DATAIN, VLAOBS, NCOUNT),
I've left other FILLM adverbs at their default values.

Enlightenment appreciated; I've CC':ed to daip in case there's
something else I'm missing,
