Thanks, Tom,
I did it yesterday before posting my question on this site, but search result was: "No topics or posts met your search criteria".

I can confer with Tom that there is a "thread" related to this question if you search all terms...

OK, you are right, thanks.
“… discrimination factor where you divide the peak height - the height of the valley by the total peak height..
So, according to this explanation, Discrimination factor = Peak-to-valley ratio?

[Uwe Neue]

The specific definition of the discrimination factor (from my book) is the ratio of the distance between the apex of the smaller peak and the valley to the height of the smaller peak.

LY, I apologize for my tone. I had just come across several other posts which had already been discussed, and it had been a long day (at least, that's my excuse!).

That’s absolutely fine, Tom, and thanks again for you consideration.
