Objective prism survey of QSO candidates in the field centered at 00 H00 M + 00° 00' paper v. discussion of survey results

Abstract

This is the last in the series of papers on our visual search for QSO candidates, using low dispersion objective prism plates obtained with 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 give 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 could not unambiguously classify it as a star, a galaxy or some other known type of object. Despite this, many of our candidates are interesting enough for follow-up slit spectroscopy. This will also provide us with useful information for improving our selection criteria.
