摘要
本文总结巡天的结果并对结果进行讨论,同时发表69个Q=3的紫外超天体的坐标,B_J~*及证认图。
This is the last in the series of papers on our visual search for QSO candidates using the low-dispersion objective prism plates obtained from the UK Schmidt Telescope. We discuss and summarize some results at the current stage of this project. As a supplement to the Q≥4 candidates published in the previous papers, we publish in this paper the subset of Q = 3 candidates which have ultraviolet excess. Our survey may suffer from many types of contamination since any object was considered as a QSO candidate if we couldn't unambiguously classify it as a star, a galaxy, or an object of any other type. Despite this, many of our candidates are interesting enough for follow-up slit spectroscopy, which will also provids us with useful information for improving our selection criteria.
