cds-question@unistra.frmultiple-starsinterferometryNine hundred eighty-nine observations of 694 binary star systems, observed by means of speckle interferometry with the 4m telescope on Cerro Tololo, are presented. Included in these observations are three new interferometric binaries and new interferometric companions to four visual binaries. These measurements, made during the period 1989-1994, comprise the 13th installment of digital results stemming from our speckle program at several major observatories, and the 23rd list since the program's inception in 1975.1996AJ....111..936Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/111/936CatalogResearchIsServedByTAP VizieR generic servicerelated-toI/107 : Washington Double Star Catalog (WDS) (Worley+ 1984)J/AJ/106/352 : ICCD speckle obs. of binary stars.
