No, what we have established is that there is no
evidence for the existence of ADoppler from pulsars
and that the Shapiro effect on pulse times falsifies
ballistic theory.

That however, doesn't tell me whether you are capable
of the simple piece of algebra required for (a) or not.
Part (b) is more complex and I don't expect you to be
able to do it, but I am curious to know if you can do
(a) because it will determine how much maths I can use
in replies. If you can't do (a), there is little point
in using any at all.
