Differences

In adverse to radio arrays, the better optical arrays currently accept alone 6 telescopes, giving poorer angel superior from the 15 baselines amid the telescopes. Most breach amalgam interferometers use the circling of the Earth to access the amount of altered baselines included in an ascertainment (see diagram on right).

Taking abstracts at altered times provides abstracts with altered telescope separations and angles after the charge for affairs added telescopes or affective the telescopes manually, as the circling of the Earth moves the telescopes to new baselines.

The use of Earth circling was discussed in detail in the 1950 cardboard A basic analysis of the radio stars in the Northern Hemisphere. Some instruments use bogus circling of the interferometer arrangement instead of Earth rotation, such as in breach appearance interferometry.
