Karazin popup.description2 The objects of research are stars, galaxies, extragalactic objects. The aim of work is the obtainment of the optical coordinates and proper motions of stars and determination of their photometric parameters and kinematic regularities of the Galaxy. The method of study is an analysis of the modern catalogues, the positional and photometric observations of the stars. The results have been presented in 10 works (5 abstracts, 5 articles) and in 5 oral reports at 3 conferences. During the reporting period the following results are obtained: 1. The analysis of the modern catalogues was carried out with goal to include these catalogues to the astrometric database. 2. A first version of the catalogue of absolute proper motions of about 280 million stars, which is covering all sky except a small area near the galactic equator and the primary analysis of this catalogue, was carried out. 3. A database containing about 350 gigabytes of information was created. The database provides a quick and efficient access to the catalogues which necessary for work. 4. The preliminary analysis of the first version of the XPM catalogue was carried out. 5. A new version of the catalogue of absolute proper motions of about 250 million stars, which covers all sky, was created. 6. An investigation of the magnitude equation in the new version of the catalogue was carried out. 7. The proper motions of stars of a new version of the XPM catalogue were compared with proper motions of the UCAC2, UCAC3 and PPMXL catalogues. 8. The parameters of mutual rotation of the XPM and the UCAC2 systems have been obtained. The results of research were partially published, partially prepared for publication, and partially are under analysis. These results can be given for using to all interested organizations and experts in the field of astrometry, celestial mechanics and stellar astronomy in Ukraine and abroad. The expected results: improvement of the relationship between Hipparcos coordinate systems and ICRS system will be probably. Product Description popup.authors Ахметов В. Корохін В. Мизніков А.
