Mostly observers do not know what sources they have or where.
SETFC will set up facets that cover the requested area fully - they will
include all of your sources. If you wish to restrict the Clean to those
sources then you can add Clean boxes in IMAGR (use OBOXFILE too so they
are remembered). There are programs that will read a source list and
construct the boxes for you - task BOXES for one.
You are not missing steps - you know too much about your field so you
want to enter extra - which BOXES will let you do (after SETFC).
Please use daip at nrao.edu - I am about to leave on vacation.
