What is FITS?
- The standard data format used in astronomy
- Stands for 'Flexible Image Transport System'
- Endorsed by NASA and the

- Much more than just another image format (such as JPEG or GIF)
- Used for the transport, analysis, and archival storage of scientific data sets
- Multi-dimensional arrays: 1D spectra, 2D images, 3D+ data cubes
- Tables containing rows and columns of information
- Header keywords provide descriptive information about the data
- Supports state-of-the-art data compression methods
- See also the descriptions on the
of Congress Web sites.
