Talk:Keck Interferometer

Is K temperature, and what is N?[edit]

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)[reply]

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)[reply]

Active?[edit]

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

Merge[edit]

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)[reply]

Merge: per my reasoning above. IvoShandor 12:13, 25 April 2007 (UTC)[reply]
