An array to receive the cartesian position (x,y,z) and the velocity (xdot, ydot, zdot).
The position is expressed in Astronomical Unit (au) and the velocity is expressed in Astronomical Unit per day (au/day).
If the target is TT-TDB, only the first element of this array will get the result. The time scale transformation TT-TDB is expressed in seconds.
If the target is TCG-TCB, only the first element of this array will get the result. The time scale transformation TCG-TCB is expressed in seconds.
If the target is Librations, the angles of the librations of the Moon are expressed in radians and their derivatives are expressed in radians per day.
