J/AJ/106/352    Speckle observations of binary stars VIII   (Hartkopf+ 1993)

ICCD speckle observations of binary stars. VIII. Measurements during 1989-1991 from the Cerro Tololo 4m telescope Hartkopf W.I., Mason B.D., Barry D.J., McAlister H.A., Bagnuolo W.G. <Astron. J. 106, 352 (1993)> =1993AJ....106..352H
ADC_Keywords: Stars, double and multiple ; Interferometry 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.

Note: This table contains measurements from the CTIO 4 m telescope, obtained during 1989 December, 1990 May and 1991 May. The coordinates, which also serve as the Washington Double Star Catalog (WDS) number are for equinox J2000.0, but position angles have not been corrected for precession and are thus based upon the equinox for the epoch of observation, shown as the fraction of the Besselian year. Accuracies for angular separation and position angle are a function of stellar magnitude, magnitude difference, separation, and observing conditions; typical values for these observations are perhaps 1-3 milliarcsec in separation and 0.1-0.2 arcsec in position angle. Colons following the values indicate measurements of somewhat reduced accuracy, usually as a result of observing fainter systems or systems of larger magnitude difference.
