Deconvolution, Restoration and Self-Calibration

Deconvolution is no different to conventional observing. When restoring, you may wish to use the same restoring beam size for all fields. Otherwise treat each pointing as a separate observation.

Much of the discussion in the self-calibration section of the `joint approach' applies equally well here. The major difference is, of course, that because the deconvolution step has been performed on the individual fields, the demos step is not required. If you have split the visibility data into separate single-pointing datasets, you will not need to use options=mosaic (although it will not hurt). Also for single-pointing datasets, if you wish to use just one or a few of the stronger fields for self-calibration, you will need to copy the resultant antenna gain tables across to the other datasets, using gpcopy.
