Next: Imaging by an Optimizing Method . ... A big advantage of this numerical integrator is its stability: the error in the semi-major axis and the eccentricity depends only on the step size and does not grow with an increasing number of time steps. ... As the integration time increases, the numerical results become more contaminated by various errors. ... A new symplectic integrator produces no secular truncation errors in the actions of a Hamiltonian system. ...

... 8, ``Celestial Mechanics'', 2002 Orbits with osculation of higher orders and their use in celestial mechanics Yu. V. Batrakov Institute of Applied Astronomy, St. Petersburg, Russia The idea of the generalized or intermediate orbits with osculation of the second and third order was proposed and considered rigorously in 1981 [1]. ... The equations of the perturbed motion in the elements of the generalized (intermediate) orbits were derived for the first time in [5,6]. ... Batrakov Yu. ...
