J/PASP/102/1392     UBV photometry from HK survey. I     (Doinidis+ 1990)

Photoelectric UBV photometry of Northern stars from the HK objective-prism survey Doinidis S.P., Beers T.C. <Publ. Astron. Soc. Pac. 102, 1392 (1990)> =1990PASP..102.1392D
ADC_Keywords: Photometry, UBV ; Stars, halo ; Stars, metal-deficient Keywords: photometry - metal-poor stars - halo stars Abstract: Photoelectric photometry is presented for a sample of 139 halo stars drawn an extension of the HK (Ca II H & K lines) objective-prism survey of Beers, Preston and Shectmann (1988ApJS...67..461) to the Northern Galactic hemisphere. The candidates for which photometry is reported here were selected to span a wide range of types, but are dominated by stars classified as type AB, A, or "metal-poor" (MP). File Summary:
