Mapping facilities in GILDAS

• The UV Table should first be sorted by task UVSORT, to obtain a UV Sorted Table.
• From the UV Sorted Table, task DFT produces images by Direct Fourier Transform, a simple way, but slow and only practical for continuum images.
• Task UVMAP produces images by gridding and Fast Fourier Transform of a UV Sorted Table.
• Task CLEAN is available for deconvolution with several variants of the CLEAN algorithm.

See the GILDAS documentation for further details.
