* The Besselian Elements are the input data needed for the algorithms of the BASIC computer program presented in the Occultations chapter of the book Astronomical Tables of the Sun, Moon and Planets by Jean Meeus. With that program one can determine local timings for occultations, and the graze latitudes for various geographic longitudes during 2010-2040.
