...as to your first point....
[typed earlier]
I'm thinking you'll now try to say that the fraction of heat lost thru collisions versus re-radiation is what is logarithmic; but....
reply to anticipated response:

For this "logarithmic heating idea" to be valid, there would have to be mostly heating via collisions (and fewer re-radiations) at the lowest concentrations; and the fewest collisions (with mostly re-radiation) at the moderate to higher concentrations.

Fewer collisions ...at the higher concentrations? Does that make sense?

I'll look at the second point now....

p.s. ...hmmmm. Maybe I didn't anticipate very well. I'll have to look at this again... sorry....
