  <shortdescription>Image-domain deconvolution</shortdescription>

​

  <description>Task deconvolve executes image-domain deconvolution with options for automasking and restoration. It can be viewed as the minor cycle of the iterative image reconstruction offered by the tclean task. The functionality that it introduces is the ability to just run the deconvolution step alone.

      <description>Pre-name of input and output images

                        example : imagename='try'

                        Input images (* = required):

                        try.psf*        - The point spread function

                        try.residual*   - The observed (or residual) image, such as one

                                          generated by tclean

                        try.model       - An existing model image from a previous run of

                                          tclean or deconvolve

                        try.mask        - A pre-defined mask to be either used directly or 

                                          combined with additional masking options

                        try.pb          - Primary beam model, if required for masking settings

                        Output images:

                        try.model       - A new or updated model image

                        try.residual    - An updated residual image

                        try.image       - A restored image, created only when restoration=True

                        try.mask        - The output mask

                        try.prev.mask   - An intermediate by-product of automasking

                                          (when usemask='auto-multithresh')

                        For multi-term wideband imaging, all relevant images above will

                        have additional .tt0,.tt1, etc suffixes to indicate Taylor terms,

                        plus the following extra input images.

                        try.alpha       - spectral index

                        try.alpha.error - estimate of error on spectral index

                        try.beta        - spectral curvature (if nterms > 2)

                        Tip :  Include a directory name in 'imagename' for all

                               output images to be sent there instead of the

                               current working directory : imagename='mydir/try'

                        Tip :  Restarting a deconvolution run without changing 'imagename'

                               implies continuation from the existing model image on disk.

                               By default, the residual image will be recomputed.

                        Note : All deconvolution runs will by default produce restored images.

                               For a niter=0 run, this will be redundant and can optionally

                               be turned off via the 'restoration=T/F' parameter.

                        Note : All input/output images should be 4D image cubes with axes

                               [ra,dec,pol,chan], as is the default for the task tclean. Any input

                               images without this format must be modified (eg with imregrid,

                               imtrans, image.adddegaxes) in order to be accepted.
