11. He specialized in astrometry , making very precise measurements of stellar positions and motions. 12. A SBIG ST8300M camera is used for Astrometry and Photometry in several observation programs. 13. The spectroscopic orbit produces far stronger constraint compared to the astrometry -only orbit. 14. After being appointed to the Astronomical Calculation Institute, Fricke concentrated on fundamental astrometry . 15. The first all-sky photographic astrometry project, magnitude but it was never completed. 16. Manca also performs follow-up astrometry of near-Earth objects ( NEOs ). 17. The observing time is mostly assigned for the photometry of asteroids and comets and astrometry . 18. He was an active astronomer who specialised in the characterisation of binary stars using astrometry . 19. Based upon parallax measurements made with the Hipparcos astrometry satellite, Hamal is about from Earth. 20. Astrometry of the innermost planet, meanwhile, constrained its inclination to 30-90 degrees.
