MAP_RESAMPLE

        [CLEAN\]MAP_RESAMPLE WhichOne [Nc Ref Val Inc] [Result] [/LIKE Mold]

    Resample 3-D data cubes on a different velocity scale.
         Nc   new number of channels
         Ref  New reference pixel
         Val  New velocity at reference pixel
         Inc  Velocity increment
    WhichOne indicates which data cube must be compressed. Allowed values are
         - Built-in buffers DIRTY, CLEAN, SKY, SINGLE or *, which means all
           of the previous existing ones. Resampling is done in place.
         - Any SIC Image Variable that is not a built-in buffer in IMAGER.
         - A GILDAS data file
    For  the  two later cases, the Result argument indicates where the resampled
    data cube is stored. Result can be a file name or an existing  SIC  variable
    of adequate dimensions.

    MAP_RESAMPLE only works on 3-D data cubes.
