      Compute  the 4 main "moments" of a data cube. If no argument is given, the
    data cube is either the SKY one (if present) or the CLEAN one. The  argument
    may  specify  a  Gildas file (when a . is present in the argument), or a SIC
    Image variable.

    The 4 moments are stored in new SIC Image variables:
    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.
