The Flexible Image Transport System (FITS) file format is a digital file format used primarily in astronomy for storing, transmitting, and analyzing scientific images and data. Developed in the late 1970s, FITS was designed to provide a standard for the interchange of astronomical data, facilitating the sharing and analysis of data among astronomers and researchers worldwide.
FTS file format is used to edit, store and transmit images with metadata (data with spatial and photometric calibrations) for scientific purposes. Most times it stores the data without the actual associated images.
