Dear David A. Smith
Thank you for your comments and the links which I will study.

The Pioneer 10 and Pioneer 11 have an unexplained very small
*deceleration* which is the same as a *negative acceleration* as in my
calculation. So I think that the direction is not wrong?
What are the measured magnitudes of the velocities of the Pioneer
Probes? Have you knowledge about that?
