The Sloan Extension for Galactic Understanding and Exploration (SEGUE)
Survey obtained ≈240,000 moderate-resolution (R ~ 1800) spectra from
3900 Å to 9000 Å of fainter Milky Way stars (14.0 < g
< 20.3) of a wide variety of spectral types, both main-sequence and
evolved objects, with the goal of studying the kinematics and
populations of our Galaxy and its halo. The spectra are clustered in 212
regions spaced over three quarters of the sky. Radial velocity
accuracies for stars are sigma (RV) sim 4 :km; s^{-1} at g < 18,
degrading to sigma (RV) sim 15:km; s^{-1} at g ~ 20. For stars with
signal-to-noise ratio >10 per resolution element, stellar atmospheric
parameters are estimated, including metallicity, surface gravity, and
effective temperature. SEGUE obtained 3500 deg2 of additional
ugriz imaging (primarily at low Galactic latitudes) providing precise
multicolor photometry (σ(g, r, i) ~ 2%), (σ(u, z) ~ 3%) and
astrometry (≈0farcs1) for spectroscopic target selection. The stellar
spectra, imaging data, and derived parameter catalogs for this survey
are publicly available as part of Sloan Digital Sky Survey Data Release
