Abstract:

It is now 16 years since the first data release from the Sloan Digital Sky Survey (SDSS; York et al. 2000). This Early Data Release, or EDR, occurred in 2001 June (Stoughton et al. 2002). Since this time, annual data releases from SDSS have become part of the landscape of astronomy, populating databases used by thousands of astronomers worldwide (Raddick et al. 2014a, 2014b), and making the SDSS’s 2.5 m Sloan Foundation Telescope (Gunn et al. 2006) one of the most productive observatories in the world (Madrid & Macchetto 2009). This paper describes the 14th public data release from SDSS, or DR14, released on 2017 July 31. The SDSS has completed three phases and is currently in its fourth phase. SDSS-I and-II conducted a Legacy survey of galaxies and quasars (York et al. 2000), the SDSS-II Supernova Survey (Frieman et al. 2008; Sako et al. 2014), and conducted observations of stars for the …
