The model I'm using is ballistic theory, I am
happy to accept ballistic theory is wrong.

My maths IS ballistic theory.

Your program provides the correct result for the
velocity curve based on the PRF as the green line,
not the red.

Funny how you agree the what ballistic theory says
about the PRF of our pulsar but you refuse to discuss
the subject, preferring to bleat on about a load of
philosophical nonsense.
