These are given by Eq. (9) for retrograde precession and by Eq. (19) for forward precession. Both types of precession obey the ECE2 antisymmetry law in the limit of vanishing magnetogravitational field, and assuming that the scalar spin connection is the universal omega sub 0 = – c / r. This is a demonstration of the fact that the ECE2 lagrangian methods and the ECE2 gravitational field equations and antisymmetry laws are rigorously self consistent, a major step forward for ECE2 theory. These calculations can be checked by computer algebra as usual and the results graphed and analyzed, both for the spin connections and gravitational vector potentials for various planar orbits. Horst is working on volume two of “Principles of ECE Theory” at present so this can be done in due course, when he has the time.
