    Option /TABLE can be used to write the sampling function  (UV  coverage)
    in  a  UV table for further processing such as producing beams using the
    task UV_MAP. Name should be specified only if  option  /FRAME  has  been
    used,  to initialize the table. Subsequent call to the UV_TRACKS command
    will append the new observation to this table. The visibilities  written
    in  the  UV table are constant, as if a point source were observed (real
    part = 1, imaginary part = 0).
