Abstract

We construct a catalogue compilation designated Large Quasar Astrometric Catalogue (LQAC) giving equatorial coordinates, multiband photometry, radio fluxes, redshift, luminosity distances and absolute magnitudes. For that construction, we gather the 12 largest quasar catalogues (4 from radio interferometry programs, 8 from optical surveys), and we carry out systematic cross-identifications of the objects. Informations concerning u, b, v, g, r, i, z, J, K photometry as well as redshift and radio fluxes at 1.4GHz, 2.3GHz, 5.0GHz, 8.4GHz and 24GHz are given when available. A small proportion of remaining objects, not reckoned by the 12 catalogues and included in the Veron-Cetty & Veron quasar catalogues, are added in the compilation.

The LQAC contains 113666 quasars. We use up-to-date cosmological parameters as well as recent models for galactic extinction and K-correction in order to evaluate the absolute magnitudes of the objects.
