Description
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 spectrograph, and a novel optical
interferometer. All of the data from SDSS-III are now made public. In
particular, this paper describes Data Release 11 (DR11) including all
data acquired through 2013 July, and Data Release 12 (DR12) adding data
acquired through 2014 July (including all data included in previous data
releases), marking the end of SDSS-III observing. Relative to our
previous public release (DR10), DR12 adds one million new spectra of
galaxies and quasars from the Baryon Oscillation Spectroscopic Survey
(BOSS) over an additional 3000 deg2 of sky, more than triples
the number of H-band spectra of stars as part of the Apache Point
Observatory (APO) Galactic Evolution Experiment (APOGEE), and includes
repeated accurate radial velocity measurements of 5500 stars from the
Multi-object APO Radial Velocity Exoplanet Large-area Survey (MARVELS).
The APOGEE outputs now include the measured abundances of 15 different
elements for each star. In total, SDSS-III added 5200 deg2 of
ugriz imaging; 155,520 spectra of 138,099 stars as part of the Sloan
Exploration of Galactic Understanding and Evolution 2 (SEGUE-2) survey;
2,497,484 BOSS spectra of 1,372,737 galaxies, 294,512 quasars, and
247,216 stars over 9376 deg2; 618,080 APOGEE spectra of
156,593 stars; and 197,040 MARVELS spectra of 5513 stars. Since its
first light in 1998, SDSS has imaged over 1/3 of the Celestial sphere in
five bands and obtained over five million astronomical spectra.
