There are no modelling of forces on the spacecraft in the paper -- construct
or otherwise.

Have you actually looked at the paper??


Yes.

They wouldn't be able to see anything without accurate modelling of the
gravitational and non-gravitational forces on the spacecraft.


You are incorrect. The paper does not deal with forces on the
spacecraft at all. Please read it.


Which part of "An important contribution to the frequency shift is due
to non-gravitational forces acting on the spacecraft" do you have a
problem reading?

Maybe my english isn'g good enough but the sentence "However, the uncertainty
in the thermal model overwhelms any plausible application of the pioneer
anomaly to Cassini." seems to me that they couldn't model arrurately enough
for the checking of the "pioneer anomaly". Thermal seems to refer to the
thermal radiation of the isotope batteries.

Lots of Greetings!
