      Compute the 4 main "moments" of the CLEAN (or SKY) data cube,  and  return
    them  as  SIC  Image variables.  SKY has priority over CLEAN if both are de-
    fined.

    The 4 moments are
    M_AREA   Integrated area over the velocity range
    M_PEAK   Peak brightness value
    M_VELO   Mean or peak velocity
    M_WIDTH  Weighted line width
    The options control the method, the selected part of the cube (default chan-
    nels from FIRST to LAST), and the threshold for detection (default 3 sigma).

    The resulting images can be displayed using command SHOW MOMENTS  and  saved
    using WRITE MOMENTS.
