|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.
