本文介绍了斯隆数字巡天（SDSS）的第五次数据发布（DR5）。DR5包括截至2005年6月的所有调查质量数据，代表了SDSS-I项目的完成（其继任者SDSS-II项目将持续到2008年中期）。它包括在8000度以上选择的2.17亿个物体的五波段光度数据，以及从5713度的成像数据中选择的1,048,960个星系、类星体和恒星的光谱。这些数字比第四次数据发布的数字增加了大约20%；以往数据发布中的所有数据均包含在本数据发布中。除了“标准的”SDSS观测外，DR5还包括对南赤道条纹的重复扫描，对M31和英仙座星系团核心的成像扫描，以及来自SEGUE的第一个光谱数据，SEGUE是一项探索银河系运动学和化学演化的调查。目录数据库包含了几个新的特征，包括星系的光度红移，成像巡天重叠区域的匹配对象表，以及允许精确计算统计调查巡天几何的工具。
This paper describes the Fifth Data Release (DR5) of the Sloan Digital Sky Survey (SDSS). DR5 includes all survey quality data taken through 2005 June and represents the completion of the SDSS-I project (whose successor, SDSS-II, will continue through mid-2008). It includes five-band photometric data for 217 million objects selected over 8000 deg2 and 1,048,960 spectra of galaxies, quasars, and stars selected from 5713 deg2 of that imaging data. These numbers represent a roughly 20% increment over those of the Fourth Data Release; all the data from previous data releases are included in the present release. In addition to "standard" SDSS observations, DR5 includes repeat scans of the southern equatorial stripe, imaging scans across M31 and the core of the Perseus Cluster of galaxies, and the first spectroscopic data from SEGUE, a survey to explore the kinematics and chemical evolution of the Galaxy. The catalog database incorporates several new features, including photometric redshifts of galaxies, tables of matched objects in overlap regions of the imaging survey, and tools that allow precise computations of survey geometry for statistical investigations.
