Table 5.1 lists the FITS extension type names and their registered status with the IAUFWG at the time this Guide is being written. Also included in the table are the organization with current responsibility for the extension and its development and, when available, a reference describing the extension. Table 5.2 explains the status codes in Table 5.1.
The up-to-date official listing of extensions registered with the IAUFWG is
available on-line from the FITS Support Office at
http://fits.gsfc.nasa.gov/xtension.html
or
ftp://nssdc.gsfc.nasa.gov/pub/fits/xtension.lis. This listing is
revised as information is received from the IAUFWG about the registration of
new type names or progress of a particular extension type through the approval
process.
