cds-question@unistra.frmetallicityvisible-astronomybroad-band-photometryhorizontal-branch-starsWe present results from an analysis of medium-resolution spectroscopy and UBV photometry for a sample of 1121 A-type stars in the halo (and disk) of the Galaxy. A previously developed calibration technique is used to assign estimates of effective temperature, surface gravity, and stellar metal abundance, as parametrized by [Fe/H]. Radial velocities are reported with an accuracy of {~}10 km.s^-1^. Distance estimates are obtained for the stars with well-determined luminosity classes. Note that although we refer to "A-type" stars, which dominate the present sample, the present data set includes roughly 100 stars of later spectral types, as a result of the temperature range we have chosen to explore in this paper (6000 K {<=} T_eff_ {<=} 10,000 K).1999AJ....117.2329Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/117/2329CatalogResearchIsServedByTAP 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.
