    Plot interferometer UV tracks as observed with the interferometer.   The
    default  is for Plateau de Bure, but the command is more general and can
    be used with any array, especially ALMA.

    Station coordinates are searched for in the  file  defined  by  the  AS-
    TRO_STATIONS  logical  variable.  Stations  should  be  referred to by a
    mnemonic (e.g. E03, W00 ...) given as arguments of UV_TRACKS.  See  also
    /STATIONS option.

    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 and used by several other commands
    in ASTRO, such as LINE or FREQUENCY).

    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.
