J/PASP/103/973     Photoelectric UBV from HK survey. II. (Doidinis+ 1991)

Photoelectric UBV photometry of northern stars from the HK objective-prism survey. II. Doidinis S.P., Beers T.C. <Publ. Astron. Soc. Pac. 103, 973 (1991)> =1991PASP..103..973D
ADC_Keywords: Photometry, UBV ; Stars, metal-deficient ; Stars, halo Keywords: UBV photometry - northern stars - HK objective-prism survey 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) 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.
