J/A+A/444/625     Photographic positions of the major planets  (Rizvanov+, 2005)

Photographic observations of Solar System bodies at the Engelhardt astronomical observatory. Rizvanov N., Nefedjev J. <Astron. Astrophys. 444, 625 (2005)> =2005A&A...444..625R
ADC_Keywords: Planets ; Positional data Keywords: astrometry - planets and satellites: general - catalogs Abstract: We describe a large database of photographic observations of Solar System bodies obtained at the Engelhadt Astronomical Observatory (EnAO). We give a brief description of the methods of observations and the accuracy of their reduction with the PPM and Tycho-2 catalogues. The photographic positions of the major planets, except Jupiter, are in the system of the Tycho-2 catalogue and their comparison with DE200 ephemeris coordinates are given. File Summary:
