Question: Does a 100m / 45m / 30m floppy dish work better?

A larger dish with a perfectly gaussian beam would certainly result in better image combination, but what if we have a poorly constrained (i.e., high sidelobe power) beam that is much smaller? John Carpenter brought up this point. We can test it using some distorted (perhaps asymmetric?) synthetic beams and see what happens.

Had some of this problem when combining Herschel. For this moment we use the shorter uv distance to alleviate the problem.
