[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.
