Journal ArticleDOI

The Seventh Data Release of the Sloan Digital Sky Survey

Kevork N. Abazajian, +223 more
TL;DR: A series of improvements to the spectroscopic reductions are described, including better flat fielding and improved wavelength calibration at the blue end, better processing of objects with extremely strong narrow emission lines, and an improved determination of stellar metallicities.
Journal ArticleDOI

Sloan digital sky survey: Early data release

Chris Stoughton, +212 more
TL;DR: The Sloan Digital Sky Survey (SDSS) is an imaging and spectroscopic survey that will eventually cover approximately one-quarter of the celestial sphere and collect spectra of ≈106 galaxies, 100,000 quasars, 30,000 stars, and 30, 000 serendipity targets as discussed by the authors.
Journal ArticleDOI

Sdss-iii: massive spectroscopic surveys of the distant universe, the milky way, and extra-solar planetary systems

Daniel J. Eisenstein, +263 more
TL;DR: SDSS-III as mentioned in this paper is a program of four spectroscopic surveys on three scientific themes: dark energy and cosmological parameters, the history and structure of the Milky Way, and the population of giant planets around other stars.
Journal ArticleDOI

The 2.5 m Telescope of the Sloan Digital Sky Survey

TL;DR: The Sloan Digital Sky Survey (SDS) as discussed by the authors is a two-corrector Ritchey-Chretien design with a 2.5 m, f/2.25 m, a 1.08 m secondary, and one of a pair of interchangeable highly aspheric correctors near the focal plane, one for imaging and the other for spectroscopy.
