Maybe we could MAKE them this way! Couple of
gigawatt masers ( one for the reference beam ) we
might MELT the aluminum for the bullseye!
Seriously, though, I'm sorry about the 7 meg file.
We got it down to 2.7 meg ( big deal ). Dr. Shuch
says he got it down to just a very few tens of kilobytes,
and that it will go onto the League site later today.
Included will be the zero-ten degree beampattern,
which shows about a -18db first sidelobe.
