Abstract
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 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. The complete photometric sample of 299 northern HK candidates obtained to date contains on order 90 main-sequence turnoff, subgiant, and giant stars with (Fe/H) of less than or equal to -1.0, 50 field blue horizontal-branch stars, and 30 stars with the photometric properties of field-blue stragglers.
