The interferometer also includes a set of four 1.8 meter diameter movable telescopes dedicated to interferometric observations.
The VLTI can work in a fully integrated way, so that interferometric observations are actually quite simple to prepare and execute.
For interferometric observations on the brightest objects, there is little benefit in using 8 meter telescopes rather than 1.8 meter telescopes.
Allais, Maurice, "New very significant regularities in the interferometric observations of Dayton C. Miller 1925-1926".
As of 2005, four of the six telescopes have been commissioned for interferometric observations.
This will be possible through a technique known as interferometric observations.
NExScI has also developed various software tools to model and plan interferometric observations and to calibrate KI data.
Spectroscopic and interferometric observations have shown that A is actually a triple system consisting of two B-type stars and a pre-main sequence star.
The interferometric and spectroscopic observations allow the distance to the system to be determined independently of other methods.
This star was observed to be double in speckle interferometric observations in 1988, but this has not been confirmed by later infrared observations.
