Digitization of Astronegatives of the Pulkovo Glass Library: Positions of Saturn's Major Satellites in the Period 1972-1982 in the Gaia DR2 System

Izmailov, I. S.; Vasil'eva, T. A.; Khovrichev, M. Yu. +3 more

We present the results of the re-reduction of Pulkovo photographic plates with images of Saturn's major satellites in the Gaia DR2 catalog system (169 plates, 3007 individual positions). Astronegatives were taken with the 26-inch refractor at the Pulkovo Observatory between 1972 and 1982. The intrinsic accuracy of measurement of astronegatives usi…

Replenishment of the database of observations of distant satellites of planets is always useful, since the accuracy of the motion models and ephemeris depends not only on the accuracy of observations. Accuracy improves with increasing observation time. Therefore, observations made even with the same accuracy are in demand. Astrometric observations…
