Quite.
I have known for a very long time before 2008 that the speed
of the star contributes nothing to _stellar_ aberration.
Here is a posting from 2003:

Read the following carefully:
Stellar aberration is the change in the angle of the beam
OBSERVED IN THE EARTH FRAME at different times of the year.
We NEVER observe the angle of the beam in the stellar frame.
It matters zip what this might be. When the star changes its
velocity (being a binary), the angle of the beam in the stellar frame
will change. But we never observe this angle so it doesn't matter.
The only thing that matters is the difference in the velocity
of the Earth frame and the resulting change of the direction in
the Earth frame.
That's why a star at the ecliptic pole is seen to move around
a circle with diameter (60km/s)/c radians.
The paper that started the discussion in 2008:

Then, Koobee Wublee
came down on him hard. Spanked him.
See Wublee spank me in 2008:

Koobee Wublee:
Allow me to claim that again. The stellar aberration is an
application of the Galilean transform for low speeds. Since the
Galilean transform satisfies the principle of relativity,
the velocity of the star is very much important in determining
this aberration. shrug
Paul B.Andersen:
It's more fun every time you repeat your blunder. :-)
Now it is breathtaking.
And I love to rub it in:
Ever since Bradley in 1725 for the fist time measured the stellar
aberration, it has been experimentally verified over and over again
that stellar aberrations depends _only_ on the change of the velocity
of the Earth, and of the speed of light. The velocity of the star
contributes nothing to stellar aberration.
The fact that the stellar aberration is the same for both
components of a binary makes it blazingly clear that the velocities
of the components are irrelevant.
Knowing this (you know it now), it is pretty stupid to claim:
"the velocity of the star is very much important in determining
this aberration."
I still love to rub it in! :-)
The small professor then accused
Koobee Wublee of confusion in parallax and aberration and wrote these
phantom papers as distraction from his blunder. What a small
professor he is indeed. shrug
See Wublee confuse parallax and aberration:

Koobee Wublee responded:

Since you think the aberration in my paper is parallax,
you have confused the two. Your blunder Koobee!
Of course, this is not the only time. Before that, paul also claimed
the correction to the GPS clock being necessary because the carrier
frequencies of the downlinks will be affected. Koobee Wublee also
came down hard on the small professor.
Again, Wublee? :-)

It is completely beside the point to repeat over and over
that the small offset in the frequencies sent from
the satellite have no consequences whatsoever,
because nobody ever said they had.
Listen autistic idiot:
The reason, and only reason, why the frequency standard is corrected
for relativistic effects is to make the SV clock run synchronously
with the ground clocks.
That the carrier and shipping frequencies also are adjusted is
just a side effect because all frequencies are derived from
the same frequency standard.
Read this:
-----------------------------------------------------------
The important point is that if the SV clock rates were not corrected,
they would drift out of sync from GPS time after few minutes.
The clocks have to be in sync within 100 ns for the GPS to work.
-------------------------------------------------------------------
The carrier frequencies, like all other frequencies,
are at the receiver Doppler shifted between +/- 3E-7.
The satellites are moving!
The Doppler shift may be almost a thousand times more than
the minute GR-correction, so of bloody course the -4.4647E-10
offset is of no consequence whatsoever for the receiver!
AND NOBODY EVER SAID OTHERWISE!
This was written in August 2007, when you already had repeated
your stupid claim a number of times.
Since then, you have repeated it again and again.
You must indeed be an autistic idiot!
Same thing happened. paul
skillfully deleted his posts and corrected his blunders by re-engaging
the discussions a few years later with a different story. shrug
So I have rewritten the Google archive? :-)
I have had my fun for now, but I am sure you yet again
will give me an opportunity to remind you of your blunders.
And the opportunity came quickly! :-)
You have made many blunders, Koobee, so if you want me
to remind you of more of them, I will be at your service.
