Thanks Gulio!
That is very useful information.
There are a lot of erroneous statements in the literature by the way (interested readers should look at some of my papers).
You mean, look there for the "erroneous statements"? :) I suppose not.
- Even when considering lines from ions 'well behaved', the largest
variations in results are coming from the use of different ion abundances.
Is there any clever way to deal with that? I've never given it much thought, but one cannot keep ignoring this...
Cheers,
