The Edinburgh-Cape Blue Object Survey - III. Zone 2; galactic latitudes-30° > b >-40°

The Edinburgh-Cape Blue Object Survey seeks to identify point sources with an ultraviolet excess. Results for zone 2 of the survey are presented here, covering that part of the South Galactic Cap between 30 degrees and 40 degrees from the Galactic plane and south of about -12 degrees.3 of declination. Edinburgh-Cape zone 2 comprises 66 UK Schmidt Telescope fields covering about 1730 deg(2), in which we find some 892 blue objects, including 423 hot subdwarfs (similar to 47 per cent); 128 white dwarfs (similar to 14 per cent); 25 cataclysmic variables (similar to 3 per cent); 119 binaries (similar to 13 per cent), mostly composed of a hot subdwarf and a main-sequence F or G star; 66 horizontal branch stars (similar to 7 per cent) and 48 'star-like' extragalactic objects (similar to 5 per cent). A further 362 stars observed in the survey, mainly low-metallicity F- and G-type stars, are also listed. Both low-dispersion spectroscopic classification and UBV photometry are presented for almost all of the hot objects and either spectroscopy or photometry (or both) for the cooler ones.
