        [CLEAN\]WRITE UV File /TRIM [ANY]

    Remove  the  flagged  visibilities  while  writing. A visibility is declared
    "flagged" if all channels in it are  flagged,  unless  the  keyword  ANY  is
    present. In this later case, if a single channel is flagged, the whole visi-
    bility is declared flagged.
