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. File Summary:

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) 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) MKL: MEKAL BR: bremsstrahlung RS: Raymond-Smith thermal model (Raymond & Smith 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.
