FITS Data Format
FITS stands for `Flexible Image Transport System' and is the standard
astronomical data format endorsed by both NASA and the IAU. FITS is
much more than an image format (such as JPG or GIF) and is
primarily designed to store scientific data sets consisting of
multi-dimensional arrays (1-D spectra, 2-D images or 3-D data cubes) and
2-dimensional tables containing rows and columns of data.
