        Plot interferometer UV coverage as  observed  with  the  interferometer.
        The  default  is  for  NOEMA, but the command is more general and can be
        used with any array, especially ALMA or SMA.

        Station coordinates are searched for in the  file  defined  by  the  AS-
        TRO_STATIONS logical variable. The default file contains NOEMA stations.
        It can be customized using the SIC LOG ASTROTIONS YouFile command.

        Some configuration files for NOEMA, ALMA, and SMA are  distributed  with
        gildas  and  can be used as ASTRO_STATIONS files combined with UV_TRACKS
        ALL to avoid typing a lot of station names (see HELP UV_TRACKS NOEMA|AL-
        MA|SMA)

        Stations should be referred to by a mnemonic (e.g. E003, W000 ...)  giv-
        en as arguments of UV_TRACKS.  Note that with  the  contruction  of  the
        NOEMA  track  extension  the mnemonic names changed from [E,N,W]+2digits
        for the station number to [E,N,W]+3digits for the station  number.   Old
        names are still accepted during a transition period.

        The size of the antennas can be specified with the /SIZE option.

        The /STATIONS option allows to use the ranks of the stations in the file
        rather than the mnemonic names.

        The coordinates of the most recently selected SOURCE or PLANET are  con-
        sidered. The frequency of the simulated observation is read from the Sic
        FREQUENCY variable (which is also set by LET FREQUENCY command).

        UV_TRACKS can be used iteratively, to simulate the observations of  sev-
        eral  configurations. Option /FRAME indicate the start of a new observa-
        tions: if not present, configurations are being stacked on  the  current
        UV  coverage.  The user may select another color pen to distringuish be-
        tween the various coverages. A sketch of the interferometer described by
        ASTRO_STATIONS  is  also  drawn,  and the selected stations/antennas are
        highlighted.
