Flexible Image Transport System (FITS)

The Flexible Image Transport System (FITS) is a standard file format used by astronomers to store, share, and analyze astronomical data such as images, spectra, and tables. Designed for high precision and reliable data transfer, FITS files encode information about the data's origin, measurement details, and calibration. This format ensures that scientific data remain consistent and usable across different software and research projects, facilitating collaboration and long-term data preservation in the astronomy community.
