Observations of Double Stars and New Pairs. XVII. Abstract image available at:http://adsabs.harvard.edu/cgi-bin/nph-bib_query?1996ApJS..105..475H&db_key=AST
| 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.
| Micrometer observations of double stars and new pairs. XII Measurements of 2132 pairs and 103 double stars, obtained in both theNorthern and Southern Hemispheres in the period June 1982 to September1984, are listed in a table. The observations were carried out using theSwarthmore College 61-cm refractor, and the 100 and 91 cm telescopes ofthe Cerro Tololo Inter-American Observatory. Corrections to the IDScatalog (1961 version) are given for some of the fainter stars in thesurvey.
