| Abstract: | The aim of the present work is to compare photographic observations of the Galilean satellites of Jupiter with the theory developed by Sampson at the beginning of the century and corrected and implemented recently by Lieske.The comparisons between the observed and computed values give differences in geocentric angular distances of the order of 0 .08 for modern observations (1968 to 1977) and of the order of 0.14 for older ones (1913 to 1928).These results lead to the suggestion that important long period defects still exist in the theory of Sampson-Lieske. This is not surprising, due to the difficulties of the computation of the long-period inequalities in mean longitudes, even in a first-order theory.Proceedings of the Conference on  Analytical Methods and Ephemerides: Theory and Observations of the Moon and Planets.
