Sloan digital sky survey: Early data release
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, 100,000Expand
The Milky Way Tomography with SDSS. II. Stellar Metallicity
In addition to optical photometry of unprecedented quality, the Sloan Digital Sky Survey (SDSS) is producing a massive spectroscopic database which already contains over 280,000 stellar spectra.Expand
Astrometry and photometry for cool dwarfs and brown dwarfs
Trigonometric parallax determinations are presented for 28 late-type dwarfs and brown dwarfs, including eight M dwarfs with spectral types between M7 and M9.5, 17 L dwarfs with spectral types betweenExpand
A Catalog of Spectroscopically Confirmed White Dwarfs from the Sloan Digital Sky Survey Data Release 4
We present a catalog of 9316 spectroscopically confirmed white dwarfs from the Sloan Digital Sky Survey Data Release 4. We have selected the stars through photometric cuts and spectroscopic modeling,Expand
Spectroscopy of giants in LMC clusters. I. Velocities, abundances, and the age-metallicity relation
Velocities and equivalent widths are presented for a large sample of LMC clusters. The calcium abundance is found to be a sensitive abundance indicator over a very wide range of (Fe/H) between 0.0Expand
Exploring the Variable Sky with the Sloan Digital Sky Survey
We quantify the variability of faint unresolved optical sources using a catalog based on multiple SDSS imaging observations. The catalog covers SDSS stripe 82, which lies along the celestial equatorExpand
The Second Data Release of the Sloan Digital Sky Survey
The Sloan Digital Sky Survey (SDSS) has validated and made publicly available its Second Data Release. This data release consists of 3324 deg2 of five-band (ugriz) imaging data with photometry forExpand
SDSS DR7 WHITE DWARF CATALOG
We present a new catalog of spectroscopically confirmed white dwarf stars from the Sloan Digital Sky Survey (SDSS) Data Release 7 spectroscopic catalog. We find 20,407 white dwarf spectra,Expand
An Improved Proper-Motion Catalog Combining USNO-B and the Sloan Digital Sky Survey
An improved proper-motion catalog is presented, combining the USNO-B and Sloan Digital Sky Survey (SDSS) catalogs in the area of sky covered by SDSS Data Release 1 (DR1; 2099 deg2). USNO-B positionsExpand
