I have a few questions.
Is there a link between Pioneer anomaly and flyby anomaly?

OK They solved Pioneer anomaly. They used thermal model of the two spacecraft Pioneer 10 and Pioneer 11.

Astrophysicist Slava G. Turyshev said

” We still have an uncertainty in our study of less than 18 percent. But for me, this is the answer. Some may argue it is not final, but in my mind we did a good job, and it's very clear what happened.”

In article we can read

” Radio metric data from the Pioneer 10/11, Galileo, and Ulysses spacecraft indicate an
apparent anomalous, constant, acceleration acting on the spacecraft with a magnitude ∼
8.5 ื 10 −8 cm/s 2 , directed towards the Sun.”

ap∼ 8.5 ื 10 −8 cm/s 2

Did they used their thermal model to explain anomaly for Galileo, and Ulysses spacecraft, or only used thermal model for Pioneer 10 and Pioneer 11?

Here is one intresting article

”Gary Page of George Mason University in Fairfax, Virginia, and his colleagues have identified 15 asteroids that might also be subjected to the mysterious force. The asteroids' orbits all stretch far into the outer ...”

Doppler residuals (observed minus computed data) is very important. Doppler residuals (frequency residuals) is linked to ap, so if anyone wants to explain anomaly, he should explain origin of Doppler residuals or ap. In case Pioneer anomaly they used thermal model.

In case fly by anomaly Doppler residuals should be explaind too.
” While the Doppler residuals (observed minus computed data) were expected to remain flat, the analysis revealed an unexpected 66 mHz shift, which corresponds to a velocity increase of 3.92 mm/s at perigee. “
