Positional and photometric supplement to the compiled GPM catalogue of proper motions of stars referred to galaxies
Rybka, S. P.
Precise positions and three-color B, V, R photometric data selected from all available sources were included into the GPM catalogue. The Tycho, GSC, and USNO-A2 catalogues are the main sources. The data were investigated for systematic and random errors and reduced to a uniform system.
Catalogue of 2450 positions of 19 selected minor planets on ICRS system obtained with the zonal astrograph at Nikolaev during 1961-1997
Gorel, G. K.; Gudkova, L. A.
Photographic positions of 19 selected minor planets (SMP), obtained with the Zonal Astrograph at Nikolaev during 1961-1997 were reduced to the ICRS system using reference stars from HIPPARCOS and Tycho star catalogues and proper motions from ACT Reference Catalogue. Rms of one position is 0.16'' in both coordinates.
Comparison between the GPM proper motions referred to galaxies and the ACT data.
Rybka, S. P.
Proper motions were derived for 4893 stars in selected areas from combination of source catalogues with galaxies. They were included into the GPM compiled catalogue and compared with the ACT data consistent with the Hipparcos reference system. The results were analysed by the analytical method developed at the Astronomisches Rechen-Institut. The s…
Determination of highly precise proper motions for 32 Hipparcos stars from photographic plates.
Wang, S.; Wang, J.; Jin, W. +1 more
The authors have reduced 70 exposures on 32 photographic plates taken in four areas of the sky around the radio source 0316+413, the galaxy NGC 7302, the Pleiades astrometric standard region, and so on with the 40-cm astrographic refractor at SheShan (Zô-Sé) Station of the Shanghai Observatory. Using the PPM catalogue as the initial reference cata…
The relative positions and proper motions of components for 32 triple stars from HIPPARCOS input catalogue.
Orlov, V. V.; Anosova, Zh. P.; Todua, M. M.
A statistical study of the astrometric data for 32 triple stars has been carried out in the frame of the program of the International working group "Double and Multiple Stars HIPPARCOS". The relative positions and proper motions of the components have been made more accurate, uncertainties of their determinations have been analysed.
