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.
