You still don't understand what stellar aberration is : (

Okay I gave it my best shot -- now be a man and give it your best shot! What do you say the difference is between "Stellar Aberration" and "Annual Aberration?"

There is no difference. That was my point.

Are you saying that WP and all the other websites that I've cited about stellar aberration and such are all wrong?

No, but your interpretation of what they are saying is wrong. Annual aberration is composed of many parts, not just one.

So which is it? Are you saying you were wrong or that WP is wrong? I mean WP could be wrong -- so why not just say so?

Why don't you just look at the pictures? The pictures and diagrams will tell you everything you need to know.

So tell me, what part of the physics book do you disagree with?

From Wiki:

“A special case of annual aberration is the nearly constant deflection of the Sun from its true position by k towards the west (as viewed from Earth), opposite to the apparent motion of the Sun along the ecliptic. This constant deflection is often erroneously explained as due to the motion of the Earth during the 8.3 minutes that it takes light to travel from the Sun to Earth: this is a valid explanation provided it is given in the Earth’s reference frame, whereas in the Sun’s reference frame the same phenomenon must be described as aberration of light. Hence it is not a coincidence that the angle of annual aberration be equal to the path swept by the Sun along the ecliptic in the time it takes for light to travel from it to the Earth (8.316746 minutes divided by one sidereal year (365.25636 days) is 20.49265”, very close to k). Similarly, one could explain the Sun’s apparent motion over the background of fixed stars as a (very large) parallax effect.”

Yeah, me and the rest of the world. I guess you're the only one who understands stellar aberration. Is that the long and the short of it? You've still failed to provide a single reference which says that my understanding is wrong or that shows that yours is correct.

Fair enough. Words only have meaning because we attribute meaning to them. As long as I know that to you "stellar aberration" and "Annual Aberration" are the same thing, then I'll know what you're talking about when you use the terms. It seems other people do use them interchangeably. But for your information, some people don't use them to mean the same thing exactly. For example, these guys at Stanford make a distinction between the two phrases.

Why don't you just look at the pictures? The pictures and diagrams will tell you everything you need to know.

then I ought to be all set.

I'd love to discuss that with you -- but AFTER we get this current issue settled. You've clearly stated that the sun is apparently displaced by 2.1 degrees for an observer on earth at any instant in time due to the fact that the earth rotates 2.1 degrees in the 8.3 lightminutes. If we can't figure out this simple geometry, there's no way we're going to do any good discussing college level physics or my book.
