Abstract:
The ESO Very Large Telescope Interferometer (VLTI) is one of the
leading interferometric facilities. It is equiped with several 8.2 and
1.8m telescopes, a large number of baselines up to 200m, and with
several subsystems designed to enable high quality measurements and to
improve significantly the limits of sensitivities currently available
to long-baseline interferometry. For this, a large number of
observations of potential calibrators have been obtained during the
commissioning phase of the VLTI. These data are publicly available.
