Scientific paper

A search was made of common proper motion (CPM) systems among AGK 3 stars. The selection of physical systems was based upon the ratio between the angular separation, ρ, and the proper motion, μ; the CPM stars found are presented in two tables: Table I lists systems with ρ/μ less than 103years. It contains 326 entries and the proportion of optical pairs is estimated to be 1%. Table II lists systems with ρ/μ in the range 1000 to 3500 years; it contains 113 systems, but only 60% of them are physical. Nevertheless these systems often have separations larger than 10000 AU and are the most interesting for the study of the tail of the distribution function of the semi-major axes.
