Paper Abstract

The Very Large Telescope Interferometers is with its four 8 m Unit Telescopes and three 1.8 m Auxiliary Telescopes, which can be located on thirty different stations, the largest and most flexible of all optical interferometers. Making efficient use of this fantastic astronomical machine requires some insight into the main components of the interferometer and their limitations. The observation preparation tools we have developed over the last two years follow the studies we have undertaken on operational constraints of VLTI operations. These constraints are, among others, sky footprints of telescopes and limitations from delay line operations and variable curvature mirror range. The tools are an aid to observers, especially in guiding to the optimum interferometric baseline, but can also be used to educate interested parties on VLTI. Observation preparation using these tools will help to maximize the scientific output from VLTI.
