Abstract Photoelectric UBV observations of 1782 stars are used to explore properties of the HK objective-prism survey conducted by Beers, Preston, and Shectman with the Curtis-Schmidt telescope of the Cerro Tololo Inter-American Observatory. An intrinsic (U-B)0 versus(B-V)0 relation for blue horizontal branch stars is constructed and used 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. Qualitative features of the stellar content of the HK survey are described by use of unreddened two-color diagrams and ways in which the photometric data may prove useful in several applications are indicated. Finally, a halo density model is employed to estimate the variation of completeness with apparent magnitude, B, in the present catalog of field horizontal branch star candidates.
