Eric,

I m trying to run SAD on an image and am getting no sources detected when I should be getting 100s.  I am working with a colleague who we both ran SAD (previous AIPS versions) on earlier data of the same field and we are likely getting something wrong on the inputs.

Can you help us out?  

Thanks,

Chris
