Title: UBV photometry of eclipsing binaries with visual companions
Abstract: Nineteen eclipsing binaries with visual companions were observed photoelectrically. Comparison stars were chosen, one for each eclipsing binary and its companion, and tied in to the UBV system. Then differential UBV magnitudes, relative to these comparison stars, were obtained for the binary, companion, and/or binary-plus-companion. Key words: eclipsing binaries - UBV photometry - visual binaries
