  We present source code for the computer algebra system Mathematica that
analyzes the motion of the Pioneer spacecraft using the public available
ephemeris data from JPL's website. Within 15 minutes, the reader can verify
that the Pioneer anomalous acceleration a_p (1) exists in the order of
magnitude of c H_0, (2) is not due to mismodeling of gravitational attraction,
solar pressure or spacecraft attitude maneuvers. The simple code of about 100
lines may easily be extended by the reader to include further tests. Due to the
limitations of our approach, we do not know (1) whether the unknown raw data
were correctly processed to generate the trajectory files (2) how the apparent
mismatch of ephemerides before 1990 had occurred.
