I am sorry for the delay in answering - I was on vacation.  The
address daip at nrao.edu reaches the full group and someone else might
have answered.

JMFIT only looks in the BLC/TRC box - so if you can limit a component
to a box unaffected by the wings of other components then you will be
okay.  But if the various components overlap, then you need to solve
all of them.
