We construct an intrinsic (U-B)0 versus (B-V)0 relation for blue horizontal branch stars and use it to derive estimates of E(B-V) color excesses in 50 survey fields. Comparison of these with the reddening maps of Burstein and Heiles indicates good agreement except in low-latitude fields toward the Galactic bulge. We describe qualitative features of the stellar content of the HK survey by use of unreddened two-color diagrams and indicate how the photometric data may prove useful in several applications. Finally, we use a halo density model to estimate the variation of completeness with apparent magnitude, B, in our catalog of field horizontal branch star candidates. 1991ApJS...76.1001P https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/76/1001 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to 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/AJ/90/2089 : Stars of very low metal abundance.
