Catalogues of Fundamental Stars
(series of astrometric catalogs from 19th century on)
The Catalogues of Fundamental Stars
are six catalogs (plus some supplements)
of astrometric data, numbered one through six
and dating from 1897 to 2000.
Each covers selected stars, on the order of a thousand.
The aim has been to establish a celestial reference frame
for use with celestial coordinate systems.
The 1963 catalog (FK4) was commonly used with B1950
equatorial coordinate system, and the 1988 catalog (FK5)
More recent celestial reference frames are based on
satellite astrometry, such as HCRF and Gaia-CRF2, and
those based on quasars, such as the ICRF,
used by the International Celestial Reference System (ICRS).
