Photographic observations of visual double stars
Mean positions, the corresponding epochs, relative separations, positionangles, and mean errors are presented for 95 pairs of visual doublestars, mostly in the Southern Hemisphere. The results were obtained bymeasuring plates taken with the 60-cm visual refractor of BosschaObservatory, Lembang, Indonesia, over a 16-yr period. The reductionmethod used in determining the mean positions, epochs, and errors isdiscussed.
