Catalogues of Fundamental Stars

+ Save concept

The Catalogue of Fundamental Stars is a series of six astrometric catalogues of high precision positional data for a small selection of stars to define a celestial reference frame, which is a standard coordinate system for measuring positions of stars. [1]

10 relations: Arthur Auwers, Astrometry, Astronomical Calculation Institute (Heidelberg University), August Kopff, Hamal, Hipparcos, International Celestial Reference Frame, Iota Arietis, Kappa Aurigae, Star.
