Abstract:
We present a catalogue of ultraluminous X-ray sources (ULXs) in
external galaxies. The aim of this catalogue is to provide easy access
to the properties of ULXs, their possible counterparts at other
wavelengths (optical, IR, and radio), and their host galaxies. The
catalogue contains 229 ULXs reported in the literature until April
2004. Most ULXs are stellar-mass-black hole X-ray binaries, but it is
not excluded that some ULXs could be intermediate-mass black holes. A
small fraction of the candidate ULXs may be background Active Galactic
Nuclei (AGN) and Supernova Remnants (SNRs). ULXs with luminosity above
1040erg/s are found in both starburst galaxies and in the halos of
early-type galaxies.

--------------------------------------------------------------------------------
Note (1): The near-infrared Ks-band magnitude is calculated from the
20mag/arcsec2 isophotal magnitude listed in the 2MASS Large Galaxy
Atlas (Jarrett et al., 2003AJ....125..525J 2003AJ....125..525J)
Note (2): The far-infrared magnitude is calculated from
FIRmag=-20.0 -2.5logFIR,
where FIR is the far infrared continuum flux measured at 60 and
100microns as listed in the IRAS Point Source Catalog (1987, Cat.
II/125).

--------------------------------------------------------------------------------
Note (1): Radius from nucleus, assuming that the galaxy center is at
the RC3 (Cat. VII/155) optical position. Only strong X-ray sources
with enough counts have X-ray spectral fits.
Note (2): The following abbreviations have been used for the fit model:
PL: power-law model
BB: blackbody
MCD: multicolor disk (Mitsuda et al., 1984PASJ...36..741M 1984PASJ...36..741M)
MKL: MEKAL
BR: bremsstrahlung
RS: Raymond-Smith thermal model (Raymond & Smith 1977ApJS...35..419R 1977ApJS...35..419R)
Note (3): If a two-component fit is needed, we use the symbol '+'
between the two fit models and fit results for the two-component best fit.
