ICCD Speckle Observations of Binary Stars. VIII. Measurements During 1989-1991 From the Cerro Tololo 4m Telescope
Abstract
One-thousand eighty-eight observations of 947 binary star systems, observed by means of speckle interferometry with the 4 m telescope on Cerro Tololo, are presented. These measurements, made during the period 1989-1991, comprise the second installment of results stemming from the expansion of our speckle program to the southern hemisphere.
