On conjugate complex time - II: equipotential effect of gravity retrodicts differential and predicts apparent anomalous rotation of the sun

Equipotential effect of gravity (EEG), as opposed to radial interactions between bodies, is introduced here as the impact of a tangential potential. EEG causes frequency decrease that was observed in two specially devised and several indirect experiments. It depends on the distance that is measured along equipotential parts of trajectories and can explain an extraneous frequency decrease found in radio signals emitted by navigational positioning systems. It retrodicts the observed differential rotation of the sun without the assumed drag of the sun's photosphere as its cause, and predicts apparent anomalous rotation of the sun, for from the shifts in spectra taken from the sun's limb it should appear as if the sun rotates away faster than it does towards an observer on earth. The value predicted by it is over 10.56% excess over Einstein's value of deflection of light near the sun and agrees with the 10-15% excess estimated from the data that was obtained in numerous, quite independent experiments.
