Abstract:
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 and 40° from the Galactic plane and south of about -12.3°
of declination. Edinburgh-Cape zone 2 comprises 66 UK Schmidt
Telescope fields covering about 1730sq.deg, in which we find some 892
blue objects, including 423 hot subdwarfs (∼47%); 128 white dwarfs
(14%); 25 cataclysmic variables (∼3%); 119 binaries (∼13%), mostly
composed of a hot subdwarf and a main-sequence F or G star; 66
horizontal branch stars (∼7%) and 48 "star-like" extragalactic objects
(∼5%). 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.
Description:
The original EC survey plan and the methods employed were laid out in
considerable detail in Paper I (Stobie et al. 1997MNRAS.287..848S 1997MNRAS.287..848S).
The completed area consists in 259 fields, 61 having been published in
Paper II (J/MNRAS/287/867). For all fields reduced, we have obtained
low-dispersion (100Å/mm) spectroscopy for the bluest objects; UBV
photometry has been obtained for many, but not all, of these. Not all
plates have been reduced, but since it is unlikely that any further
photometry will be completed, it is our intention to publish what
material we have as quickly as possible.

Note (1): Brief comments on:
* the quality of the photometry or spectroscopy, including comments
on the spectral classification or variability;
* the comments 'hsp' or '2hsp' indicate that 'high-speed' (continuous)
photometry has been obtained on one or more occasions.
* comments from some collaborative projects on apparently normal B-stars
and CVs which give additional photometry, spectroscopy or analyses
(temperatures, gravities, abundances etc.)
* some alternative designations are listed, including spectral types
from the literature or Simbad when available
