In reference to the Pioneer Anomaly
the most definite conclusion is based on the JPL report:
http://arxiv.org/abs/1204.2507

[[Mod. note -- Published as Phys Rev Lett 108, 241101.

The same authors' (Rutyshev et al) previous paper,
arXiv:1107.2886 = Phys Rev Lett 107, 081103,
is also essential reading.

This reference is key;
Note Figure 1
The top panel represents modeling
daP/dt = -k*aP model one
and the bottom panel
daP/dt = -k*(aP - aPinfinity) model two
It is clearly evident that model two predominates.

The thermal modelling is discussed in more detail in
Rievers et al, New J Physcs 11, 113032
http://dx.doi.org/10.1088/1367-2630/11/11/113032

Presented data was below 45 AU where thermal effects predominate.

It does not reflect the thermal and Doppler solutions over time.
With time, the constant Doppler solution
dominates the decaying thermal solution
as the Pioneers approach interstellar space.
The Doppler solution is real
versus
the 1000s of calculated decaying internal finite element
diminishing contributions.

This JPL analysis failure unnecessarily negates a major contribution
to science.
I am not talking about new physics but a confirmation of space time.
The JPL report has a geocentric/heliocentric view
and dismisses the universal view.

The JPL analysis is based on incomplete analysis of the data
assuming the decay for Pioneer acceleration aP

daP/dt = -k*aP model one

This fits the assumption that
the thousands of analyzed aP thermal components
are tied to the RTG half life with aP decay approaching zero with time.

A better fit to trajectory data is the 'aPinfinity' effect
as the Pioneers approached interstellar space:

daP/dt = -k*(aP - aPinfinity) model two

Initially, as the Pioneers pass Jupiter,
the thermal emission overwhelms
the anomalous acceleration (aPinfinity)
making it statistically insignificalt in this initial trajectory phase
but diminishes with time(model one)
with aP decay approaching aPinfinity
with time (model two)
as the Pioneers probe interstellar, intergalactic space
on leaving the solar system
with diminished internal thermal and external solar wind
considerations previously considered.

Statistically significant aPinfinity values a
Pioneer 10 aPinfinity 7.0x10^-10 m/sec^2
Pioneer 11 aPinfinity 8.2x10^-10 m/sec^2

These values may represent a constant for interstellar medium
within some standard deviation
or actually represent different values based on
differing Pioneer 10 and 11 directional probes of interstellar medium.
The interstellar medium may not be uniform.

Logically, in as much as aPinfinity
is a measure of space-Pioneer momentum transfer (spacetime viscosity)
then all transiting object motion would be affected.
This has implication for galactic and planetary system formation
as reflected in accelerations associated
with the Tully Fischer relationship.

Apparently there is still some unpublished Pioneer data
to further test this hypothesis.
Considering this data's importance to the scientific community,
it should be published.
