On the Use of Statistical Parallaxes for the Proper Motion Reductionseclination. The proper motions and reductions with use of galaxies were derived for all areas. The errors of reductions are equal to ± 0..006. In addition the statistical reductions R., R. were computed for the control and for the zones of avoidance. The following formulae were used: . where . is th

On the Programme of Ground-Based Observations of Bright Selected Minor Planets for 1991–2000The programme of observations of 10 bright minor planets for 1991–2000 is proposed. One of the main aims of the programme is the determination of the orientation parameters and the systematic errors of star catalogues.
