Have you still not learned the difference between refraction and gravitational deflection, Laurence? Do you remember that you made fool of yourself when you claimed that Poor said that Einstein's equation was "a refraction formula"? What Poor said was: "The mathematical formula, by which Einstein calculated his deflection of 1.75 seconds for light rays passing the edge of the sun, is a well known and simple formula of physical optics" The equation Θ = 4GM/Δ⋅c² is a gravitational deflection formula, but since you think it is "a refraction formula" you can try to use it to explain why the Sun is seen above the horizon when it really is below it. Good luck! :-D -- Paul https://paulba.no/
