我们描述了用于银河系探索和理解的斯隆扩展(SEGUE)恒星参数管道(SSPP)的开发和实现。SSPP是利用多种技术、径向速度和AFGK型恒星的基本恒星大气参数(有效温度、表面重力和金属丰度)，基于最初的斯隆数字巡天(SDSS-I)及其银河系延伸(SDSS-II/SEGUE)过程中获得的中分辨率光谱和UGRIZ测光技术得出的。SSPP还为范围更广的恒星提供光谱分类，包括窗外温度的恒星，在这些恒星中，大气参数可以用目前的方法估计。这是关于SSPP的系列论文中的第一篇；它提供了SSPP的概述，并使用几个外部数据集对其性能进行了测试。对当前版本的SSPP的随机和系统误差进行了严格的检查，该版本已用于SDSS(DR-6)的第六次公开数据发布。
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).
