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

The eleventh and twelfth data releases of the Sloan Digital Sky Survey: final data from SDSS-III

Shadab Alam, +363 more
TL;DR: The third generation of the Sloan Digital Sky Survey (SDSS-III) took data from 2008 to 2014 using the original SDSS wide-field imager, the original and an upgraded multi-object fiber-fed optical spectrograph, a new near-infrared high-resolution spectrogram, and a novel optical interferometer.

The Eleventh and Twelfth Data Releases of the Sloan Digital Sky Survey: Final Data from SDSS-III

Shadab Alam, +273 more
TL;DR: The third generation of the Sloan Digital Sky Survey (SDSS-III) took data from 2008 to 2014 using the original SDSS wide-field imager, the original and an upgraded multi-object fiber-fed optical spectrograph, a new near-infrared high-resolution spectrogram, and a novel optical interferometer as discussed by the authors.
Journal ArticleDOI

The Sixth Data Release of the Sloan Digital Sky Survey

Jennifer K. Adelman-McCarthy, +173 more
TL;DR: The Sixth Data Release of the Sloan Digital Sky Survey (SDS) as discussed by the authors contains images and parameters of roughly 287 million objects over 9583 deg(2), including scans over a large range of Galactic latitudes and longitudes.
Journal ArticleDOI

The Eighth Data Release of the Sloan Digital Sky Survey: First Data from SDSS-III

Hiroaki Aihara, +194 more
TL;DR: The first data release of SDSS-III is described in this article, which includes five-band imaging of roughly 5200 deg2 in the southern Galactic cap, bringing the total footprint of the Sloan Digital Sky Survey imaging to 14,555 deg2, or over a third of the Celestial Sphere.
