Abstract:
Position angle and separation measures of 482 primarily southern
binary stars are presented. These were obtained from speckle
observations taken at the Carlos U. Cesco Observatory, El Leoncito,
Argentina, using a multianode microchannel array detector during the
period 1994 July to 1996 July.
Description:
A total of eight observing runs were completed with the 0.76m
telescope at the Carlos U. Cesco Observatory (jointly operated by Yale
Southern Observatory and the Universidad Nacional de San Juan,
Argentina).

a = Quadrant ambiguous, but consistent with previous measures in the
Fourth Interferometric Catalog (Hartkopf, McAlister, and Mason

b = Quadrant ambiguous, but inconsistent with previous measures in the
Fourth Interferometric Catalog.
c = Quadrant unambiguous, but inconsistent with previous measures in the
Fourth Interferometric Catalog.
d = Quadrant unambiguous, but consistency with previous observations is
difficult to determine.
e = Quadrant ambiguous, but consistency with previous observations is
difficult to determine.
