Scientific paper

Bordeaux Observatory is participating in photographic observations of asteroids, the purpose being to point out systematic errors in equatorial coordinates of stars. The asteroids belong to the "Selected Minor Planets" list. The rectilinear coordinates of both asteroids and reference stars are sent to the Leningrad Theoretical Astronomy Institute. We publish here the equatorial coordinates of the observed minor planets. In order to improve our knowledge of the astronomical constants, great care must be taken to obtain accurate positions of the major planets and their satellites. Likewise, accurate astrometry of the moon on stellar background is essential to determine the ephemeris time. For best accuracy in positions of satellites some plates were taken with 14" photographic equatorial of 6.80 m focus and reduced like photographic double stars.
The present work follows up other papers already published in "Astronomy and Astrophysics Supplement Series".
