Photometric and astrometric observations of close visual binaries
The first photoelectric sequence for the magnitude differences of 215close visual binaries in the Johnson UBV and Stromgren uvby systems havebeen established. In addition, the position angle and the separation of140 stars were measured. Finally, for 134 stars, new photoelectricmeasurements of the combined integral brightness of both components inthe UBV and Stromgren systems were made. The measurements were carriedout using the area scanning technique.
