All-sky compiled catalogue of 2.5 million stars

Kharchenko, N. V.

The all-sky Compiled Catalogue of more than 2.5 million stars with the limiting magnitude V ≈14(m) was created as a result of combining of star lists from present-day large high-precision catalogues of space (HIPPARCOS Tycho family catalogues) and ground-based (PPM, CMC11) observations and reducing them to the standard systems of corresponding ste…

Comparison of the GPM proper motions with the data from modern astrometric catalogues

Rybka, S. P.

Proper motions, positions, B, V magnitudes and (B-V) colors from the GPM catalogue were compared with those from the Lick NPM1, the Carlsberg CMC, and the ESA "Tycho-2" catalogues. It turned out that the systematic differences of proper motions were in the range from 2 to 4 mas/yr. The external data also proved that the accuracy of the GPM proper …

New version of the latitude set derived from observations with a prismatic astrolabe in Poltava

Khalyavina, L. Ya.; Kislitsa, K. M.; Borisyuk, T. Ye. +1 more

The latitude set derived from observations with the prismatic astrolabe in Poltava during 37 years (1964.5--2000.9) is revised in order to improve the reliability and validity of the observation results. To this purpose the accurate coordinates of the HIPPARCOS catalogue are used, and the method is applied which takes into account the instrumental…
