SEGUE恒星参数管道。I.描述和初始确认测试
The SEGUE Stellar Parameter Pipeline. I. Description and Initial Validation Tests
摘要：
我们描述了SEGUE（斯隆银河系探索和理解扩展）恒星参数管道（SSPP）的开发和实施。SSPP使用多种技术，根据原始斯隆数字巡天（SDSS-I）及其银河系扩展（SDSS-II/SEGUE）过程中获得的中分辨率光谱学和$ugriz$光度学，推导AFGK型恒星的径向速度和基本恒星大气参数（有效温度、表面重力和金属丰度）。SSPP还为更广泛的恒星提供光谱分类，包括温度在窗口之外的恒星，其中大气参数可以用当前方法估计。这是一系列关于SSPP的论文中的第一篇;它提供了SSPP的概述，以及使用多个数据集对其性能进行的初步测试。随机和系统误差严格审查的SSPP，已被用于第六次公开数据发布的SDSS（DR-6）的当前版本。
英文摘要：
We describe the development and implementation of the SEGUE (Sloan Extension for Galactic Exploration and Understanding) Stellar Parameter Pipeline (SSPP). The SSPP derives, 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 of 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 initial tests of its performance using multiple 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).
