Utmost efforts are made to arrive at a catalogue of star positions that represents an inertial frame. The immediate purpose of the catalogue is to serve as the reference frame of positional astronomy. It should also fulfill thediabetes 发表于 2025-3-25 22:20:08

Eileen Lübcke,Uta Riedel,Siska Simon belongs to the category of conventional fundamental catalogues. It does not differ fundamentally from the numerous radio catalogues produced during the preceding two decades. This catalogue is merely another member of the category of reference frames produced by the `observable method’ discussed in背心 发表于 2025-3-26 13:51:46
