SPW /CHUNK

    [NOEMAOFFLINE\]SPW /CHUNK ChunkList

    Define  spectral  windows  by defining directly the chunks to be used by
    their numbers. This mode is available only when a single Baseband (even-
    tually in dual polarization) is selected with the BASEBAND command.

    The ChunkList follows the SIC\FOR list format. For example:
      SPW /CHUNK  1  5  10 TO 12
    will add 3 more spectral windows:
    - one new spw with the chunk #1,
    - one new spw with the chunk #5,
    - one new spw with the chunks #10, 11, and 12.
