FITS file format

FITS (Flexible Image Transport System) is a data file format used in astronomy. It is designed to store and transmit scientific data, including images, spectra, and tables. FITS files consist of a text header that contains metadata about the data, followed by the binary data itself. The format is widely used in the astronomical community for storing and sharing observational data. FITS files can contain multiple extensions, including image data, tables, and metadata, making them a versatile format for astronomical data analysis.
