Abstract
This document describes the registration of the Multipurpose Internet
Mail Extensions (MIME) sub-types to be used by the international
astronomical community for the interchange of Flexible Image
Transport System (FITS) files. The encoding is defined by the
published FITS standard documents. The FITS format has been in use
since 1979, and almost all data from astronomical observations are
interchanged by using FITS.
