Binary star speckle measurements during 1992-1997 from the SAO 6-m and 1-mtelescopes in Zelenchuk

We present the results of speckle interferometric measurements of binary st ars made with the television photon-counting camera at the 6-m Big Azimutha l Telescope (BTA) and 1-m telescope of the special Astrophysical Observator y (SAO) between August 1992 and May 1997. The data contain 89 observations of 62 star systems on the large telescope and 21 on the smaller one. For th e 6-m aperture 18 systems remained unresolved. The measured angular separat ion ranged from 39 mas, two times above the BTA diffraction limit, to 1593 mas.
