Beam size and position angle
Posted: Thu Nov 25, 2010 5:02 pm
Hello Jamie,
This is a general question.
Is there a way of finding the beam size and position angle from the uv data? I would normally use INVERT, RESTOR, or IMFIT to get the values.
But for a particular set of 7 mm data, when I include ca06 it doesn't calculate the beam size or position angle if cell=0.05, if cell=0.1 the beam shape is incorrect.
So I wanted to check what the uv data would give me. The problem doesn't occur when ca06 is not included.
Thanks.
Cheers
Catarina
