Cartesian orbital equations in a planet fixed (rotating) frame.
The gravity function returns the gravitational accelerations in the
planet fixed frame. It must be of the form
a = GravFun( r, gFunData )
where a is in the planet fixed frame. d.mu is not used in this case.
The planet rotation is around the ECI z axis.
The default data structure is for the the moon.
Since version 2015.2
