Mark,

Of course you right about 10 meters.

I thought first of all about the side lobes level inside of the given circle 
in the sky. 

Rotation of the array can not increase the worst side lobe inside of
the given circle in the sky even for the long track beam.

The configurations which we want to have give simmetrical UV coverage 
for snapshot. At least those configurations which I created gives very 
symmetrical coverage. I think long tracks will not destroy the symmetry.

So rotation of the array should conserve the UV coverage including 
the long tracks case.

Thank you
