I think I used most of the parameters in the document you posted, you could also try the Lorentzian qpproximation. It is hard to say though since I only have one page to work from and it doesn’t say what type of model it is using. You can look at our help file which is accessed by the component properties window and see the background theory and references we use. You should be able to match the parameters with those from your reference.
