Talk:Keck Interferometer

Is K temperature, and what is N?

K and N need explaining here: On the 85 m Keck-Keck baseline, the Keck Interferometer will have a spatial resolution of 5 milliarcseconds (mas) at 2.2 micrometres (µm), and 24 mas at 10 µm. In its most sensitive configuration, the interferometer would reach K=21 and N=10 mag in 1000 seconds of integration (SNR = 10 per baseline). - the text is a straight copy from Nasa, but I found no explanation there either. SNR appears to be signal to noise ratio, but I'm unclear what "per baseline" means. Any pointers? -213.219.141.119 23:15, 4 September 2006 (UTC)

K and N are apparent magnitudes through the astronomical K and N filters, which are at 2.2 microns and 10 microns respectively (so they match the resolutions given previously in your quote). See also [1]. I'm not sure what "per baseline" is doing there, since there's only one baseline (the 85 m telescope separation) involved. -- Coneslayer 12:32, 25 April 2007 (UTC)

Active?

I think this project is active now, the article should reflect that. IvoShandor 10:29, 25 April 2007 (UTC)

Merge

Besides this material needing updating it would be much more useful if it were merged with Keck Observatory since the Interferometer uses the existing facilities at the observatory. IvoShandor 12:13, 25 April 2007 (UTC)
