cds-question@unistra.frvisible-astronomybroad-band-photometrypeculiar-variable-starspopulation-ii-starsWe present photoelectric UBV photometry for some 2600 metal-poor dwarf and giant candidates selected from the HK objective-prism/interference-filter survey of Beers and colleagues. These data provide the basis for our ultraviolet-excess selection of objects having [Fe/H]{<~}-2.0 for a spectroscopic investigation in which we have obtained ~1-2{AA} resolution spectra of some 1000 objects. The present material may also prove useful for investigations of the metal-poor dwarfs and giants more metal-rich than [Fe/H]=-2.0, as well as the misclassified subdwarf O and B stars, white dwarfs, blue metal-poor stars, and field horizontal-branch stars which appear in the catalog.1999ApJS..123..639Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/123/639CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/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/AJ/90/2089 : Stars of very low metal abundance.
