<shortdescription>Task for single-dish image processing</shortdescription>
Task sdfixscan is used to remove a scanning noise that appears
as a striped noise pattern along the scan direction in a raster
By default, the scanning noise is removed by using the
FFT-based 'Basket-Weaving' method (Emerson \& Grave 1988) that
requires multiple images that observed exactly the same area with
different scanning direction. If only one image is available, the
'Pressed-out' method (Sofue \& Reich 1979) can be used to remove
