Image Deconvolution

The CLEAN method is the major image deconvolution method available in GILDAS (several variants can be used). Recently, a new deconvolution method, WIPE, has been implemented in MAPPING .

• CLEAN
  The CLEAN task implements several variants: the basic algorithm as described by HOGBOM, the CLARK modification which cleans most of the image, and a Multi-Resolution-Clean (MRC). The HOGBOM and CLARK methods allow both the image and the beam to be 3-D cubes. For the MRC method the same beam must be used to clean all planes.

• MX
  The MX tasks implements a variant of the CLARK method, where clean components are substracted from the visibilities at each major cycles, rather than from the map. Aliased sidelobes are therefore suppressed.

• MAPPING
  is an interactive deconvolution program described below. MAPPING is more flexible and more powerful than CLEAN, and allows proper deconvolution of Mosaics. MAPPING includes new deconvolution methods like WIPE. MAPPING also includes interactive UV editing.
