cds-question@unistra.frvisible-astronomybroad-band-photometryhalo-starschemically-peculiar-starsPhotoelectric 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).1990PASP..102.1392Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASP/102/1392CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/118 : UBVRI standards around Celestial Equator (Landolt 1983)J/AJ/87/1515 : UBV photometry of AB stars in halo (Pier, 1982)J/ApJS/53/791 : Spectroscopy of AB stars in halo (Pier, 1983)J/ApJS/76/1001 : UBV photometry of HK survey stars (Preston+, 1991)J/PASP/103/973 : Photoelectric UBV from HK survey.
