There you are Henry, we have derived an upper limit
on the extinction distance from the published data.
Now you understand what I was driving at, and
hopefully you also realise I really did understand
your model all along :-)

While some stars may have more or less dense plasma
around them, in general the distance should be around
that sort of level for all and shorter for stars with
a dense plasma. Note that it is much less than the
distance to the heliopause for the Sun.

George, I don't have a firm view as to why my distances are always shorter
than
the actual ones....but there must obviously be a simple explanation.

The simple explanation is that SR is correct. From
your point of view though, as light passes through
a plasma we know it is affected and that could cause
some change to the speed. The obvious explanation
would be that absorption and re-emission at each
atom encountered immediately changes the speed to c
relative to that atom, but that would eliminate any
effects so your problem is why the extinction distance
isn't the mean path length.

The fact that so many brightness curves are reproducable using BaTh is
enough
to keep me convinced I'm right.

I think other factors are operating here.

There are no "other factors" in Ritzian theory to
operate aside from those already in your program.
You still need to fix that bug in the velocity
curve though.

There is no bug.

See my other post for details.

Circular orbits can appear slightly elliptical and vice versa.

Perhaps, but whether the distortion caused by variable
speed exactly eliminates that caused by Kepler's Second
Law is something you should show mathematically, and I
don't believe you can do that. As a result I think you
will find there remains a slight distortion even for
your best fit.

"When a true genius appears in the world, you may know
him by this sign, that the dunces are all in confederacy against him."

Hmm but a genius in physics is unlikely to need to get
the dunces to integrate an exponential for him. Remember
your "challenge" that I solved in a few lines?

That is really your biggest problem, you don't seem to
have the familiarity with maths that you need to follow
a lot of the arguments. At the moment you seem to be
struggling with the wavelength to velocity conversion
for your blue line for example. Anyway, see if my latest
attempt to explain it lets the penny drop and we'll see
where that takes your program.
