A catalogue of faint, UV-excess objects

Spectra, positions, magnitudes and colours are presented for 1400 faint (B < ∼ 21 mag) stellar objects identified in a complete, ultraviolet-excess (UVX) survey. The objects were selected from COSMOS machine measurements of UK Schmidt U and J plates and observed with the Fibre Optic Coupled Aperture Plate (FOCAP) system at the Anglo-Australian Telescope (AAT). In total, 420 QSOs were identified, of which nine belong to the broad absorption line (BAL) class of QSOs. A further 57 galaxies with narrow emission lines were found. Halo subdwarfs form the vast majority (∼90 per cent) of the 824 galactic stars identified in this survey; the remaining galactic stars are comprised principally of hot white dwarfs (42 objects) and horizontal branch stars (nine objects). Update versions of the QSO number-magnitude relation and luminosity function derived from this survey are also presented in this paper. (author)
