    Option  /FRAME  [size]  should  be  used  to start a new UV coverage. It
    clears the plot, draws the box, and  open  a  new  table  if  /TABLE  is
    present.  'size'  is  the maximum UV spacing plotted, in meters (default
    800 m). Subsequent call to the command (without  /FRAME)  adds  the  new
    configurations.
