Catalogue of Apparent Diameters and Absolute Radii of Stars (CADARS) - Third edition - Comments and statistics
The Catalogue, available at the Centre de Données Stellaires deStrasbourg, consists of 13 573 records concerning the results obtainedfrom different methods for 7778 stars, reported in the literature. Thefollowing data are listed for each star: identifications, apparentmagnitude, spectral type, apparent diameter in arcsec, absolute radiusin solar units, method of determination, reference, remarks. Commentsand statistics obtained from CADARS are given. The Catalogue isavailable in electronic form at the CDS via anonymous ftp tocdsarc.u-strasbg.fr (130.79.128.5) or viahttp://cdsweb.u-strasbg.fr/cgi-bin/qcar?J/A+A/367/521

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.
