Current performance[edit]

As far as I know SUSI only operates with baselines up to 160 meters. Longer ones should be commissionned soon. SUSI: an update on instrumental developments and science.


This page is quite non hard-core astronomer unfriendly. I can recognize a few of the wavebands but the rest are mysteries to me. And attempts to lookup wavebands in Wikipedia seem to return nothing (maybe a shortcoming in wikipedia). I would like to suggest that a complete review of the article be done to identify terms which may only be well understood by astronomers and provide links to (or create) pages for definitions that can be interpreted by people with a good science education but a lack of training in the sub-discipline of astronomy. For example -- what frequency ranges are the J H and K bands (among others) include! -- this could easily be resolved by the creation of a wikipedia "wavebands" page. It is useful to not that if one is going to include an informative table -- one should provide links to explanations for what the columns are discussing (to the best extent possible) for non experts to be able to follow the discussion. —Preceding unsigned comment added by RobertBradbury (talkcontribs) 17:12, 3 December 2009 (UTC)


It would also be useful to have a multi-part discussion of the limits of interferometers. Part (a) would discuss the math involved in reconstructing reasonable images; part (b) would discuss the limits that are required to detect objects of certain sizes at certain distances. For example -- how far apart would the detectors need to be (at what distances in terms of l.y.) to actually see the construction of the Pyramids on earth? Or the Empire State building? And of course how far apart or at what distances could advanced technological civilizations actually "watch" individuals walking around on the streets of New York? (assuming solar-system scales) where the information might be quasi-real time -- but not galactic scales where the information would be ancient history. —Preceding unsigned comment added by RobertBradbury (talkcontribs) 17:23, 3 December 2009 (UTC)


PRIMA has now been officially abandoned by ESO so it should not appear anymore in the list. On the other hand, PIONIER is available on the VLTI with 4 telescopes and should be added. — Preceding unsigned comment added by (talk) 13:59, 7 August 2014 (UTC)
