Abstract:
    Spectra, positions, magnitudes and colours are presented for 1400
    faint (B≲21mag) 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 from 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). Updated versions of the QSO
    number-magnitude relation and luminosity function derived from this
    survey are also presented in this paper.

Note (1): the object designations (for table 6) are as follows:
    QSO = Qso with broad emission lines,
   QSO? = possible QSO,
   BALQ = broad absorption line QSO,
     NL = narrow emission line object,
   CONT = object with continuum spectrum.
   Comp = composite
Note (2): Redshift quality is numbered as follows:
      1 = certain  redshift
      2 = probable redshift; e.g. usually obtained from one strong line and
          additional low signal-to-noise lines visible
      3 = uncertain redshift; e.g. only one strong line or only low
          signal-to-noise lines visible
