The Large, Bright QSO Survey. V. QSOs in Three Southern Fields

This is the fifth and final paper in a series reporting the results of a program aimed at selecting ~1000 QSOs brighter than B_J_~ 18.75 using machine-scanned direct and objective-prism plates from the UK Schmidt Telescope. The plate material is scanned at the Automated Plate Measuring facility. The candidate list is derived using a number of complementary selection algorithms ranging from "traditional" criteria, such as the presence of strong emission features, to criteria designed to select objects whose objective-prism spectra cannot be classified as normal stars, although they may possess no obvious QSO-like features. Follow-up spectroscopy at the 2.5 m duPont telescope of the Las Campanas Observatory is used to classify each candidate. In this paper we present results from three UK Schmidt Telescope fields in which 200 QSOs have been found, 182 of which form part of the LBQS sample. Coordinates, magnitudes, redshifts, and spectra of moderate resolution and signal-to- noise ratio are given for all 200 QSOs as well as for 3 additional extragalactic objects which fail to meet our absolute magnitude criterion as QSOs.
