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
