Hi,
I have been having a problem when I run FILLM. Everytime I go to load a
certain data set I get a few spectral line sets that have no visibilities.
It may be something wrong with the data but I am not sure. Here are the
FILLM inputs and the image head for one of the data sets. Thanks for any
help you can give me. Let me know if there is any more info that you need to
address this problem!
