Precise positions, separations, and position angles of visual binaries
Astrometric observations of 212 large visual binaries are reported. Dataobtained with a GG 495 yellow filter on IIaD photographic plates usingthe Zen astrograph (aperture 20 cm and focal length 2077 mm) of theOsservatorio Astronomico di Brera during 1985-1986 are presented inextensive tables. The potential significance of these measurements forthe catalog being constructed for the Hipparcos space observatory isindicated.
