Description
We describe the development and implementation of the Sloan Extension
for Galactic Exploration and Understanding (SEGUE) Stellar Parameter
Pipeline (SSPP). The SSPP is derived, using multiple techniques, radial
velocities, and the fundamental stellar atmospheric parameters
(effective temperature, surface gravity, and metallicity) for AFGK-type
stars, based on medium-resolution spectroscopy and ugriz photometry
obtained during the course of the original Sloan Digital Sky Survey
(SDSS-I) and its Galactic extension (SDSS-II/SEGUE). The SSPP also
provides spectral classification for a much wider range of stars,
including stars with temperatures outside the window where atmospheric
parameters can be estimated with the current approaches. This is Paper I
in a series of papers on the SSPP; it provides an overview of the SSPP,
and tests of its performance using several external data sets. Random
and systematic errors are critically examined for the current version of
the SSPP, which has been used for the sixth public data release of the
SDSS (DR-6).
