Abstract:
Nine hundred eighty-nine observations of 694 binary star systems,
observed by means of speckle interferometry with the 4m telescope on
Cerro Tololo, are presented. Included in these observations are three
new interferometric binaries and new interferometric companions to
four visual binaries. These measurements, made during the period
1989-1994, comprise the 13th installment of digital results stemming
from our speckle program at several major observatories, and the 23rd
list since the program's inception in 1975.

--------------------------------------------------------------------------------
Note on WDS:
The coordinates, which serve as the Washington Double Star Catalog
(WDS) number, are for equinox 2000.0, but position angles have not
been corrected for precession and are thus based upon the equinox
for the epoch of observation (field Date).
Note on HD/DM:
DM designations are BD numbers for declinations north of -21 deg,
CPD numbers for stars further south.
Note on Theta, Rho:
Accuracies are a function of stellar magnitude, magnitude
difference, separation, and observing conditions; typical values for
these observations are 1-3 mas in Rho and 0.1-0.2 deg in Theta.
Colons following Theta or Rho values indicate measurements of
somewhat reduced accuracy, usually the result of observing fainter
systems or systems of larger magnitude difference.
