Description
This catalog contains a compilation of measurements of binary stars discovered by Paul Couteau between 1951 and 1993. For each star, it contains a reference number to identify the star in the catalog, the Cou number, the visual magnitudes of the components, positions for 1900, 1950, and 2000, the identification of the star in the BD or in the Carte du Ciel, the magnitude from that catalog, remarks such as the proper motion, a system to which the binary belongs or its position with respect to a neighboring BD star and for many stars, the spectral type. For each observation, the data given are the date, position angle, separation, telescope size, number of observations, and the observer. Sometimes the magnitudes estimated by the observer are also given. The present description DOES NOT replace the documents referenced above. It just provides a short format description of the files making up this catalogue.
