本文介绍了光学干涉测量交换格式（OIFITS）的第2版，该格式用于交换来自光学（可见光或红外）干涉仪的校准数据。这个iau认可的标准已经在过去和现在的大多数光学干涉仪项目中使用了10年，包括COAST， NPOI， IOTA， CHARA， VLTI， PTI和Keck干涉仪。软件可用于读取，写入和合并OIFITS文件。此版本2提供了附加数据表的定义（例如偏振测量），解决了未来干涉测量仪器的需求。还包括数据列，用于更严格地描述测量误差及其相关性。在这一点上，本文是朝着设计光学干涉测量通用数据模型迈出的一步。最后，主要的OIFITS头扩展了几个新的关键字，总结了内容，以便进行数据库搜索。
This paper describes version 2 of the Optical Interferometry exchange Format (OIFITS), the standard for exchanging calibrated data from optical (visible or infrared) interferometers. This IAU-endorsed standard has been in use for 10 years at most of the past and current optical interferometer projects, including COAST, NPOI, IOTA, CHARA, VLTI, PTI and the Keck interferometer. Software is available for reading, writing and merging OIFITS files. This version 2 provides definitions of additional data tables (for example for polarisation measurements), addressing the needs of future interferometric instruments. Also included are data columns for a more rigorous description of measurement errors and their correlations. In that, this document is a step towards the design of a common data model for optical interferometry. Finally, the main OIFITS header is expanded with several new keywords summarising the content to allow doing data base searches.
