Before revision: where x is radially outward from the target body, y is along the orbit track of the target body, and z is along the orbital angular momentum vector of the target body (i.e.
After revision: where is the orbital rate (/period) of the target body, is the radius of the target body's circular orbit, is the standard gravitational parameter, is radiall outward from the target body, y is along the orbit track of the target body, and is along the orbital angular momentum vector of the target body (i.e.
