ICCD Speckle Observations of Binary Stars. II. Measurements During 1982 -1985 from the Kitt Peak 4 CM Telescope
This paper represents the continuation of a systematic program of binary star speckle interferometry initiated at the 4 m telescope on Kitt Peak in late 1975. Between 1975 and 1981, the observations were obtained with a photographic speckle camera, the data from which were reduced by optical analog methods. In mid-1982, a new speckle camera employing an intensified charge-coupled device as the detector continued the program and necessitated the development of new digital procedures for reducing and analyzing speckle data. The camera and the data-processing techniques are described herein. The authors present 2780 new measurements of 1012 binary and multiple star systems, including the first direct resolution of 64 systems, for the interval 1982 through 1985.
