The Optical Interferometry exchange format (OIFITS) is the standard for exchanging calibrated data from astronomical optical (visible or infrared) interferometers. This IAU-endorsed standard has been in use for 15 years at most of the past and current optical interferometer projects, including COAST, NPOI, IOTA, CHARA, VLTI, PTI and the Keck interferometer.
