Micrometer measurements of visual binaries
A total of 376 micrometer measurements of 116 visual binaries made atthe Nice Observatory, France, in the years 1980-1983 is presented. Eachpair is identified by the A.D.S. number, the name of the couple, and theB.D. number. The next line gives the I.D.S. number, the A.D.S.magnitudes, and the spectral types. This is followed by the epoch of theobservation, the observed position angle and distance of the components,and the aperture of the refractor used. The means and the residuals fromknown orbits are given in the next lines. The symbol 'N' denotes thatthe observations were made with a 74-cm refractor; the symbol 'n'denotes a 50-cm refractor.
