Principles of a Coded Numbering System and its Application to Open Clustersut many drawbacks when using and intersecting catalogues on magnetic tapes. Thus we developed a coded system of identification with the two basic conditions that it allows to include in the files stars with all possible Kinds of numbering found in the literature, and that computer use was as simple as possible (Nermilliod, 1973).

A Bibliography of Astronomical Catalogues and the Organization of Stellar Designationsreated for this bibliography could serve as a useful guide to the assignment and subsequent citation of catalogued objects. This in turn would help those compiling inverted files of stellar objects such as the Catalog of Stellar Identifications.

Ultraviolet Photometry from the S2/68 Observations in the TD1 Satelliteed ultraviolet colours enable determination of interstellar reddening, spectral type and luminosity. This photometric system has been evaluated by comparing these parameters with other classification parameters.

Thus, among the earliest applications in the last half century was the use by L. J. Comrie at the Greenwich Observatory of Holle

Thoughts on the Form of Presentation of Star Catalogue Datarmation from equatorial coordinates to galactic coordinates — and proper motion components — is rather simple, and due to the exact definition of the galactic system, galactic coordinates and proper motion components can be given with the same accuracy as equatorial ones. Since it is data in the gal

A Bibliography of Astronomical Catalogues and the Organization of Stellar Designationsations has shown that there is an urgent need to control the use of designation notation. It is suggested that a small data base, similar to the one created for this bibliography could serve as a useful guide to the assignment and subsequent citation of catalogued objects. This in turn would help th

Desiderata for the Catalogue of Nearby Stars. The catalogue lists all stars with parallaxes equal to or larger than 07045. Only 1049 of these objects are nearer than 20 pc. The “Catalogue of Stars within 25 pc of the Sun”, published 1970 in the Royal Observatory Annals No. 5 consists of 1744 systems of which 1566 trigonometric parallaxes.
