Exo-Dat是一个数据库和信息系统，主要用于支持对流旋转和行星凌日（CoRoT）使命的系外行星方案。在CoRoT指向的方向上，它为几组数据提供了统一的接口：恒星公布的星表，在使命准备期间获得的光度和光谱数据，来自使命和后续观测的结果，以及几个特定任务的技术参数。新的光度数据构成了Exo-Cat子目录，并给出了1400万颗恒星的一致四色光度，在r-滤波器中的完整性为19等。它覆盖了银河平面上围绕CoRoT点的几个区域，总面积为209平方度。这一Exo-Dat信息系统通过提供额外的补充信息，如关于星星基本参数或其在大型CoRoT测光罩内的污染程度的先验知识，为正在进行的CoRoT光变曲线分析和地面后续行动提供必要的技术支持。该数据库与VO工具完全接口，因此受益于现有的可视化和分析工具，如TOPCAT或ALADIN。CoRoT社区可以通过网络访问它，并将逐步向公众开放。它是准备对系外行星系统的性质进行可预见的统计研究的理想工具。作为一个VO兼容的系统，这样的分析可以受益于最新的分类工具。
Exo-Dat is a database and an information system created primarily in support of the exoplanet program of the COnvection ROtation & planetary Transits (CoRoT) mission. In the directions of CoRoT pointings, it provides a united interface to several sets of data: stellar published catalogs, photometric and spectroscopic data obtained during the mission preparation, results from the mission and from follow-up observations, and several mission-specific technical parameters. The new photometric data constitute the subcatalog Exo-Cat, and give consistent 4-color photometry of 14.0 million stars with a completeness to 19th magnitude in the r-filter. It covers several zones in the galactic plane around CoRoT pointings, with a total area of 209 deg2. This Exo-Dat information system provides essential technical support to the ongoing CoRoT light-curve analyses and ground-based follow-up by supplying additional complementary information such as the prior knowledge of the star's fundamental parameters or its contamination level inside the large CoRoT photometric mask. The database is fully interfaced with VO tools and thus benefits from existing visualization and analysis tools like TOPCAT or ALADIN. It is accessible to the CoRoT community through the Web, and will be gradually opened to the public. It is the ideal tool to prepare the foreseen statistical studies of the properties of the exoplanetary systems. As a VO-compliant system, such analyses could thus benefit from the most up-to-date classifier tools.
