[Difx-users] complex support

[Reynolds, Cormac (CASS, Kensington WA)]

I have had some success with complex dual sideband using the trunk
version of DiFX. I found it did not work with the current difx-2.6, but
as Chris mentioned, he has identified the required patch and plans to
do a new 2.6.? with the missing elements from trunk.

cheers,
Cormac.
