Does anyone have any thoughts on the phenomenon of stellar aberration? It was discovered by James Bradley in 1725 when he was looking for stellar parallax and is said to be conclusive proof that the earth orbits the sun.

The second link is giving me a headache to read. I'll finish it tomorrow, but right now I am curious as to why the effects cannot be consistently predicted.
" The exact position where a star appears in the sky does not only depends on the coordinates of the source observed, but also on the observer's relative velocity. The observer velocity is responsible for a phenomenon called "Bradley aberration" or "Stellar aberration". Stellar aberration is a well known phenomenon among astronomers. It was discovered by the astronomer James Bradley  in 1727. It is claimed to be caused by the relative transverse motion between the earth and the star emitting the photons.
Some authors [2-5] have shown that this prediction is not fully compatible with observations. There is no available explanation for the fact that, while the observational data on stellar aberration are compatible with a moving earth, the symmetric description, when the star (and not the observer) possesses the relative transverse motion, does not apparently lead to observations compatible with predictions."
(From the second link in the OP.)
If the supposed motion of the planet and the range to sun remain the same and the speed of light is correct, you should be able to correctly predict all the measurements.
