    If you are cleaning the fields individually with APCLN, then they
are being treated completely separately.  They may overlap in any way
you want.  The resultant Clean Components are not, however, usable as
a group for something like a run of CALIB, if any of the Cleaning
areas overlap.  BTW - I am not sure of the scientific validity of this
approach - sidelobes from one area appear in other areas and APCLN
will have to treat those sidelobes as sources while IMAGR will treat
them as sidelobes.
