My first inclination was simply to tell you that OMFIT is not known to
work.  But I tried to debug it instead.  I have found really bad
coding that reuses in part variables that should not be reused etc.
As a consequence, I see no way in which the program can accept inputs.
I guess my first inclination was correct.

You could consider UVFIT which we do support, imaging with IMAGR
followed by IMFIT or JMFIT, or you could use the excellent
interactive fitting in the difmap package.

Ketan attempted to put all of AIPS inside OMFOT but apparently
neglected to get the basic modes working.
