The key conclusion, with error estimates: We performed 10^4 Monte Carlo iterations, which easily ensures the convergence of the result. The thermal acceleration estimate yielded by the simulation for an instant 26 years after launch, with a 95% probability, is a(t=26) = (5.8 ± 1.3) × 10^−10 ms^-2. ... These results account for between 44% and 96% of the reported value a = (8.74 ± 1.33) × 10^−10 ms^-2 (which, we recall, was obtained under the hypothesis of a constant acceleration) — thus giving a strong indication of the preponderant contribution of thermal effects to the Pioneer anomaly. http://arxiv.org/abs/1103.5222 http://arxiv.org/abs/1103.5222
