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 Gaia mission

T. Prusti, +624 more
TL;DR: Gaia as discussed by the authors is a cornerstone mission in the science programme of the European Space Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the original interferometric concept was changed to a direct-imaging approach.
Journal ArticleDOI

Gaia Data Release 1 Summary of the astrometric, photometric, and survey properties

Anthony G. A. Brown, +590 more
TL;DR: The first Gaia data release, Gaia DR1 as discussed by the authors, consists of three components: a primary astrometric data set which contains the positions, parallaxes, and mean proper motions for about 2 million of the brightest stars in common with the Hipparcos and Tycho-2 catalogues.
Journal ArticleDOI

SEGUE: A SPECTROSCOPIC SURVEY OF 240,000 STARS WITH g = 14-20

Brian Yanny, +112 more
TL;DR: The Sloan Extension for Galactic Understanding and Exploration (SEGUE) Survey as mentioned in this paper obtained approximately 240,000 moderate-resolution spectra from 3900 to 9000 of fainter Milky Way stars (14.0 10 per resolution element).
