The Hamburg Quasar Survey - III. Further new bright quasars

We present a further list of 274 bright QSOs, 106 (195) of which have B les s than or similar to 17 (17.5), selected semiautomatically from objective p rism plates taken with the Calar Alto 80 cm Schmidt telescope. All QSOs hav e been confirmed by follow-up spectroscopy and we display their flux-calibr ated spectra. We also discuss the completeness of our search technique and demonstrate that for 0.1 less than or equal to z < 3.2 and B less than or e qual to 17 we have been able to recover roughly 85% of known QSOs; 10% were lost due to overlaps while 5% were lost during the selection process. In p articular the bright z greater than or equal to 2 QSOs (17 with B less than or similar to 17) are potential targets for follow-up spectroscopy both at high-resolution from the ground and in the ultraviolet from space.
