| Tiivistelmä: | The Hipparcos measurements are to determine star positions with an unprecedented accuracy. The on-ground treatment of these satellite data is the most complex data-analysis problem ever undertaken in the history of astrometry. The consortium of European scientific institutes will compile a final and highly accurate catalogue of star positions, distances and motions. |
