J/AJ/120/1120       Speckle interferometry at USNO. VI.      (Mason+, 2000)

Speckle interferometry at the US Naval Observatory. VI. Mason B.D., Hartkopf W.I., Holdenried E.R., Rafferty T.J., Wycoff G.L., Hennessy G.S., Hall D.M., Urban S.E., Corbin T.E. <Astron. J. 120, 1120 (2000)> =2000AJ....120.1120M
ADC_Keywords: Stars, double and multiple ; Interferometry ; Magnitudes Keywords: binaries: general - binaries: visual - techniques: interferometric Abstract: The results of 1068 speckle interferometric observations of double stars, made with the 26 inch (0.66 m) refractor of the US Naval Observatory, are presented. These observations are averaged into 841 means of 815 binary stars. The systems range in separation from 0.22" to 6.01" with a mean separation of 2.21" and have a limiting secondary magnitude of V=12.5. This is the sixth in a series of papers presenting measures obtained with this system, and it covers the period 1999 January 1 through 2000 January 9. File Summary:
