J/AJ/119/3071       Speckle interferometry at USNO. V.       (Douglass+, 2000)

Speckle interferometry at the US naval observatory. V. Douglass G.G., Mason B.D., Rafferty T.J., Holdenried E.R., Germain M.E. <Astron. J. 119, 3071 (2000)> =2000AJ....119.3071D
ADC_Keywords: Stars, double and multiple ; Interferometry ; Magnitudes Keywords: binaries: general - binaries: visual - techniques: interferometric Abstract: The results of 1544 speckle interferometric observations of 637 binary stars, ranging in separation from 0.25" to 5.25", are tabulated. These observations were obtained using the 66 cm refractor at the US Naval Observatory in Washington, DC, with an intensified CCD detector. This is the fifth in a series of papers presenting measures obtained with this system and covers the period 1998 January 1 through December 31. Random errors for all measures are estimated to be 17.6 mas in separation and 0.55°/ρ in position angle, where ρ is the separation in arcseconds. File Summary:
