本文介绍了 OI（光学干涉测量）交换格式，这是一种用于交换光学（可见光/红外）恒星干涉仪校准数据的标准。该标准基于灵活图像传输系统 (FITS)，支持光学干涉观测值的存储，包括平方能见度和闭合相位数据产品，这些数据产品未包含在 UV-FITS 等无线电干涉测量标准中。该格式已经获得了大多数当前运行的光学干涉仪项目的支持，包括 COAST、NPOI、IOTA、CHARA、VLTI、PTI 和 Keck 干涉仪，并得到了 IAU 光学干涉仪工作组的认可。软件可用于读取、写入和合并 OI Exchange 格式文件。
This paper describes the OI (Optical Interferometry) Exchange Format, a standard for exchanging calibrated data from optical (visible/infrared) stellar interferometers. The standard is based on the Flexible Image Transport System (FITS) and supports the storage of optical interferometric observables, including squared visibility and closure phase—data products not included in radio interferometry standards such as UV‐FITS. The format has already gained the support of most currently operating optical interferometer projects, including COAST, NPOI, IOTA, CHARA, VLTI, PTI, and the Keck Interferometer, and is endorsed by the IAU Working Group on Optical Interferometry. Software is available for reading, writing, and the merging of OI Exchange Format files.
