Photographic observations of visual double stars.
Abstract
Mean positions, the corresponding epochs, relative separations, position angles, and mean errors are presented for 95 pairs of visual double stars, mostly in the Southern Hemisphere. The results were obtained by measuring plates taken with the 60-cm visual refractor of Bosscha Observatory, Lembang, Indonesia, over a 16-yr period. The reduction method used in determining the mean positions, epochs, and errors is discussed.
