The large, bright QSO survey. IV - QSOs in two equatorial fields
This is the fourth paper in a series aimed at selecting about 1000 QSOs brighter than B(J) about 18.7 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...[Show more]
