Abstract:
Coordinates and brightness estimates are presented for 4408 candidate
field horizontal-branch stars selected using an objective-prism,
interference-filter survey technique. The candidates lie primarily in
the southern Galactic hemisphere, and are distributed in color over
the range B-V from -0.2 to 0.40. Previous spectroscopic observation of
a subset of these candidates indicates that roughly 85 percent of the
catalog objects are bona fide members of the field blue horizontal
branch. The remaining candidates include, in order of frequency, stars
with main-sequence gravity which are likely to be a mix of
metal-deficient turnoff stars and field blue stragglers, metallic line
(Am) stars, A stars of near-solar metallicity, and high-luminosity or
binary stars.

Note (1): Object identified as BPS CS FFFFF-NNN in Simbad.
Note (2): Brightness estimate code as follows:
1 = vb, very bright
2 = b, bright
3 = mb, medium bright
4 = m, medium
5 = mf, medium faint
6 = f, faint
7 = vf, very faint
Note (3): Classification based on the CaIIK line (the FHB stars show weak
CaII K but strong Hε line):
AB (5) = no CaII K feature is apparent
A (6) = CaII K feature is discernible
