An Etymological Dictionary of Astronomy and Astrophysics

A technique in radio interferometry in which the individual telescopes are not directly
connected together, but instead make their observations separately with very accurate timings. The data are later sent to a central correlator to be combined. With this technique the individual telescopes can be arbitrarily far apart, and so the technique provides the highest resolution images in astronomy, typically down to a few milliarcseconds.
