I used a wrong declination of the source in UVCON that I forgot to change from
my previous VLA testing.
My new test shows circular symmety. You are right. I am sorry.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The synthesize beam has a circular shape at the levels of >15%.
The synthesize beam has a hexagon shape at the level of 5-10%
The hexagon shape is related probably with the three tail spiral.
