Speckle Interferometry at the US Naval Observatory. VIII.
The results of 2044 speckle interferometric observations of doublestars, made with the 26 inch (66 cm) refractor of the US NavalObservatory, are presented. Each speckle interferometric observation ofa system represents a combination of over a thousand short-exposureimages. These observations are averaged into 1399 mean positions andrange in separation from 0.16" to 14.97", with a mean separation of2.51". This is the eighth in a series of papers presenting measuresobtained with this system and covers the period 2001 March 18 through2001 December 30.
| 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.
