Thanks.  I understand it now - the legs mainly show up as interference 
between the blockage pattern and the Airy pattern and it doesn't make 
any difference whether the Airy pattern is that of its own dish or the 
other one, so you see both crosses in the V*A patterns. 

Do your calculations include the signals scattered by the legs or just 
the blockage?

I agree.
