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

III collaboration, Aihara, Hiroaki, Prieto, Carlos Allende et al.

Understand

The Sloan Digital Sky Survey (SDSS) started a new phase in August 2008, with new instrumentation and new surveys focused on Galactic structure and chemical evolution, measurements of the baryon oscillation feature in the clustering of galaxies and the quasar Ly alpha forest, and a radial velocity search for planets around ~8000 stars.

  • This paper describes the first data release of SDSS-III (and the eighth counting from the beginning of the SDSS).
  • The release includes five-band imaging of roughly 5200 deg^2 in the Southern Galactic Cap, bringing the total footprint of the SDSS imaging to 14,555 deg^2, or over a third of the Celestial Sphere.
  • All the imaging data have been reprocessed with an improved sky-subtraction algorithm and a final, self-consistent photometric recalibration and flat-field determination.
