        VLBI

        Track a single position for VLBI.

        This observing mode must not be used for other (non-VLBI) observations.

        Some special behaviours are asscociated with the observing mode VLBI:
         - The scan has only one subscan on the (fixed) source position.
         - This subscan will be executed for up to 1 hour.
           In practice it is ended, when the START command is executed for the
           next observation, e.g., when a new VLBI scan, or a POINTING or FOCUS
           is started.
         - Normally, the VLBI field system sends the commands
           SOURCE ...
           VLBI
           START
           directly to paKo, which is running in a special terminal window.  The
           field system sends these commands for the next scan (immediately)
           after the VLBI data recording for the current VLBI target source
           (for the currant scan) is finished.
