Abstract:
This is the second paper of a series describing the Asiago-ESO/RASS
QSO survey, a project aimed at the construction of an all-sky,
statistically well defined sample of very bright QSOs (BJ≤15). Such a
survey is required to remove the present uncertainties about the
properties of the local QSO population and constitutes an homogeneous
database for detailed evolutionary studies of active galactic nuclei
(AGNs). We present here the complete southern sample, which comprises
243 bright (12.60≤BJ≤15.13) QSO candidates at high galactic
latitudes (|bgal|≥30°). The area covered by the survey is
5660deg2. Spectroscopy for the 137 still unidentified objects has
been obtained. The total number of AGNs turns out to be 11163 of which
are new identifications. The properties of the selection are
discussed. The completeness and the success rate for this survey at
the final stage are 63% and 46%, respectively.
