Landau mean value

Hi,
I'm working on my diploma thesis evaluating nuclear physics data with root.

When I fit a Landau function to my histogram with fixed upper and lower limits the fit parameters show the most probable value, the sigma, the chisquare, and the constant. Is there a possibility to get the mean value either printed in the parameter list or shown in the root command line?

With respect to the question from 2002 (see below) is there a function that gives a relation between these two values when having fixed limits? Unfortunately, the question hasn't been discussed further on.

Yours, Yvonne

Hi jacek,
Does it make sense? The mean value depends where you cut the tails Rene Brun
