Abstract:
Photoelectric UBV photometry is presented for a sample of 165 stars
drawn from the extension of the HK objective-prism/interference-filter
survey of Beers, Preston and Shectman (1985AJ.....90.2089B 1985AJ.....90.2089B) to the
northern galactic hemisphere. These results are part of continuing
follow-up observations of candidate metal-deficient and
horizontal-branch field stars and other interesting stars identified
in the survey. A complete set of photometric observations is now
available for three of the 25-square-degree survey fields. We estimate
that the complete photometric sample of 299 northern HK candidates
obtained to date contains on order 90 main-sequences turnoff,
subgiant, and giant stars with [Fe/H]≤-1.0, 50 field blue
horizontal-branch stars, and 30 stars with the photometric properties
of field blue stragglers.

Note (1): the classification codes are:
MP = Metal Poor
A = A type spectrum
B = B type spectrum
C = Continuous spectrum
AB = AB type spectrum
E = Emission lines detected
P = Peculiar
Colons indicate uncertainty in the classification.
Dual classifications indicate intermediate cases.
