So, Anderson concluded that the velocity filtration model needed to be  
redone with Coulomb collisions included. Dorelly and Scudder came back  
in 2003 with a paper concluding that "the electron heat flux is  
determined by the essentially collisionless high-energy tail" of the  
distribution:

Does that mean the coulomb collisions don't really affect prediction  
of energy transport? I haven't followed the trail of citations any  
farther...
