Introduction
------------
Extensions to the basic FITS format can be defined as specified in
Grosbol et al. (Astron. Astrophys. Suppl. 73, p359-364, 1988). The IAU
FITS Working Group (WG) under Commission 5 registers the names of such
conforming extensions. The status of a given extension can have one of
the following levels:

S Standard FITS extension accepted by the IAU FITS WG
and recommended by the IAU.
P Proposal for FITS extension accepted by local FITS
committees but not yet by the IAU FITS WG.
D Draft proposal to be discussed in local FITS commitees.
R Reserved FITS extension name for which a full draft proposal
has not yet been submitted.

The table below gives a list of known names of FITS extension formats,
