5.6 Making Deconvolution Masks or Box Regions

For most careful imaging, you will want to restrict the region over which you allow CLEAN components to be found. To do this, you can create a ’deconvolution region’ or ’mask’ image using the boxit or the viewer. Note that clean can take simple boxes or box files as direct input to its mask parameter, so these tasks are most useful when direct input to clean (or use of interactive clean) will not suffice.

There are two ways to construct region files or mask images for use in deconvolution. The boxit task will find a set of box regions based upon an input image and control parameters.
