Abstract:
The Basic Fifth Fundamental Catalogue (FK5) Part I provides improved
mean positions and proper motions for the 1535 classical fundamental
stars that had been included in the FK3 and FK4 catalogs. The machine
version of the catalog contains the positions and proper motions of
the Basic FK5 stars for the epochs and equinoxes J2000.0 and B1950.0,
the mean epochs of individual observed right ascensions and
declinations used to determine the final positions, the mean errors of
the final positions and proper motions for the reported epochs, and
ancillary data such as magnitudes, spectral types, parallaxes, radial
velocities, and cross identifications to other catalog designations.
Introduction:
The Basic FK5 is the successor to the FK4 (Fricke & Kopff 1963) and
contains the 1535 classical fundamental stars used to define the
latter system. It represents a revision of the FK4 and results from
the determination of systematic and individual corrections to the mean
positions and proper motions of the FK4, the elimination of the error
in the FK4 equinox, and the introduction of the IAU (1976) system of
astronomical constants. About 300 catalogs providing star positions
obtained from throughout the world are included in the FK5. This
document should be used only to supplement the information contained
in the source reference. The latter should be consulted for more
detailed information regarding the motivation for construction of the
FK5, the determination of its equator and equinox, the expressions for
general precession, a discussion of the FK5 system, systematic
differences between the FK4 and FK5, the transformation of
observational catalogs to the FK5 system and to the reference system
J2000.0, and more thorough descriptions of the data contained in the
FK5 catalog.

Note on FK5:
These numbers have remained the same from the FK3 and FK4 (Catalog <I/15>).
The user should note that the file is ordered by FK5 number, which
means that the stars are arranged neither by right ascension nor by
declination.
Note on RAs, RAs1950, DEs, DEs1950:
The terms of elliptic aberration have been eliminated from the mean
positions. The B1950.0 data have been computed from the J2000.0 data
using a procedure described in the source reference (Fricke et al. 1988)
based on the IAU (1976) system of astronomical constants (see also
Lieske 1979).
Note on EpRA-1900, EpDE-1900:
Mean epoch (-1900.0) of the individual observed right ascensions and
declinations.
Note on e_RAs and e_DEs:
The mean errors of the positions at the mean epoch and of the
corresponding proper-motion components, as obtained from the solution of
the normal equations within the derivations of individual positions and
proper motions. (These mean errors do not include those of the FK5
system and of the equinox and equator.)
Note on Vmag:
Photoelectric magnitudes on the UBV system, as taken from the catalogs
of Nicolet (1975, 1978). Variability is indicated by a flag in byte 129.
For physical double stars, the magnitudes of the brighter components are
given (both are given in the published catalog).
Note on n_Vmag:
Where magnitude ranges are given in the published catalog, the brighter
magnitude is given and byte 129 contains an upper case "V". A lower case
"v" is present if there is variability and that letter is present in the
published catalog (amplitude exceeds 0.3mag). A "D" code indicates that
the magnitudes of two close components are given as a footnote in the
published catalog. Only the first of the two is contained in the
magnitude field of the machine-readable catalog.
Note on SpType:
A one-dimensional spectral type taken from the FK4 catalog. These types
are from the Henry Draper Catalogue (Cannon & Pickering 1918-24). For
binary and multiple systems where spectral types are known for more than
one component, a second spectral type may be given following a plus
sign.
Note on plx:
Trigonometric parallax if known (blank otherwise). These data are
taken from a preliminary version of the new Yale parallax catalog
(van Altena, Lee, & Hoffleit, in preparation). Negative parallaxes
present in the Yale catalog have been omitted here because they are
of no use in computing apparent places from the mean positions.
Note on RV:
Radial Velocity if known (blank otherwise)
Note on DM: the prefixes are
BD: Bonner Durchmusterung (Argelander 1859-62, Kuestner 1903)
SD: Southern Durchmusterung (Schoenfeld 1886)
CD: Cordoba Durchmusterung (Thome 1892-1932)
CP: Cape Photographic Durchmusterung (Gill & Kapteyn 1895-1900)
--------------------------------------------------------------------------------
History:
The following format changes were made by W. H. Warren Jr. (with Dr.
Schwan's concurrence):
The DM identifiers, which were single-digit numerical codes, were
changed to the literal codes.
Plus signs were added to the trigonometric-parallax data, even though
no negative parallaxes are included in the catalog, to indicate
that negative parallaxes are possible.
Multiple blanks between data fields were removed, as were blanks
beyond the end of each record, to decrease the logical record
length from 220 bytes to 190 bytes.
Acknowledgments:
Dr. H. Schwan kindly supplied the original and revised versions of the
on magnetic tape and colleagues at the Astronomisches Rechen-Institut
generously reviewed a draft copy of the original documentation prior to
its final release for distribution with machine-readable copies of the
catalog, and Dr. Schwan returned comments and corrections. Appreciation
is expressed to Dr. William M. Owen Jr. of JPL for supplying the
machine-readable FK4, DM cross index that was used to insert DM numbers
into the original version of the FK5 catalog.
