Observations of double stars and new pairs. XIV
Results of a continuing survey of visual double stars are presented,including 4880 measurements made from February 1987 to November 1989.The positions in WDS format and Durchmusterung numbers are given for 194pairs first reported here. Micrometer measurements of 1142 doubles madewith the Swarthmore 61 cm refractor are presented. Magnitudes areestimated for some of the objects. Plate measurements, plateorientations, position angles, number of nights, and measured exposuresare given. Visual observations of 342 pairs obtained in May 1989 atCerro Tololo, mostly with the 1.0 m reflector, are reported.
| Locations of the components of triple star systems north of +70 deg
Micrometric measurements of triple systems north of +70 deg declinationwere made with the 10.5-inch Fraunhofer refractor of Munich UniversityObservatory. Absolute positions of all measured components were derivedby using the positions of the main stars as given in the catalog AGK3and, in some cases, also in the SAO-catalog.
