摘要：

A simple device to check the individual accuracies of planet and particle trajectories in symplectic integration is proposed, and some tests are presented. Although the significant new feature of the method is that it provides information about the accuracies of massless particle orbits, it can also be usefully applied to objects with finite mass.
