Accelerated schedule?

I see that the article was edited in November 2006, when the construction dates were updated. Still, the intro to the article has construction starting in 2010 and complete in 2013.

According to this press release at Brookhaven, announcing a $14.2M grant to the LSST, the years should be 2009 and 2012.

I haven't changed the article. ChrisWinter 16:04, 6 January 2007 (UTC)[reply]

I'd be inclined to leave it. These things are more commonly late than early. —Preceding unsigned comment added by 71.41.210.146 (talk) 03:13, 29 January 2008 (UTC)[reply]
That's a 2005 press release. 2007 data claims September, 2015 (assuming they get funding). http://www.bnl.gov/npp/docs/doehep07/oconnor_LSST%2004-17-2007.pdf Article updated. 71.41.210.146 (talk) 07:21, 29 January 2008 (UTC)[reply]


The official schedule is for engineering first light in 2014, scientific first light in 2015. I have never edited a wikipedia page before, -i would be very grateful if someone replaced the telescope graphic with the more recent, correct design as per this page here contact me for more image resolutions and angles.

Updates (to be merged into article)

M2 has been cast[1] and generated.[2] M1/M3 is currently being generated: M1 has been rough ground, and M3 is being rough ground.[3] It is expected to be finished in early 2012.[4] 71.41.210.146 (talk) 06:44, 14 April 2010 (UTC)[reply]

Engineering first light

I may be uninformed, but I have no idea what the term "engineering first light" means. I can guess, but would it be better if someone re-wrote this section so that it is in plain English which avoids jargon? --95.115.190.59 (talk) 00:20, 13 January 2011 (UTC)[reply]

Note to self: LSST software is open source, worth adding to article.

I saw it described in this Symmetry article. Apparently, it's already running the Hyper Suprime-Cam on the Subaru Telescope.

Sources for the software itself (which is GPL2):

I don't have time to make elegant prose of this; if someone beats me to it, go for it! 71.41.210.146 (talk) 12:25, 25 August 2014 (UTC)[reply]

How effective will it be for UV

Can we say why it was designed to reach into the near UV (or is that standard for observatories at this altitude?), and how effective it might be ? - Rod57 (talk) 16:36, 24 April 2018 (UTC)[reply]

u filters like LSST will use are very common: SDSS had a similar one. The current best estimates of the LSST filter response curves (including losses from the atmosphere) are in this plot, but I'm not sure if the copyright/license on it would allow us to included it in Wikipedia. - Parejkoj (talk) 17:07, 27 April 2018 (UTC)[reply]
@Rod57: One of the survey bands will be u (320.5–393.5 nm[5]), which is near-UV, so the telescope is definitely designed to reach there. u-band images will be part of the survey product, and the project wouldn't include it if it weren't scientifically useful. I don't understand your question "How effective it might be?" well enough to give a quantitative answer; LSST talks about the limiting magnitude of 5σ detected stars, which is 23.53 for the u band, which is worse than gri (24.77 for g) and better than zy (22.42 for y).[6] 23.83.37.241 (talk) 10:09, 6 May 2018 (UTC)[reply]
