| Numerically integrated ephemerides of the solar system and the Moon require very accurate integrations of systems of second order ordinary differential equations. We present a new family of 8-9 pairs and assess the performance of two new 8-9 pairs on the equations used to create the ephemeris DE102. Part of this work is the introduction of these equations as a test problem for integrators of initial value ordinary differential equations. |
