Sum of two Landau plus Gauss noise for an Energy Loss Distribution

Just the simple correction you told me yesterday allows me (assumed that i initiated all the parameters in a very very very wise way) to obtain directly the right kind of plot (see attachement).

Now the problem is that if i go fine with FitPanel and iterate to best fitting, the curves L1, L2 and gauss they stay the same, they don’t update like of course the FIT red line does… it should be easy to fix that though. I’ll try myself but any help is highly appreciated. But THANK YOU

I think that this script can end up to be of great help to whom use the Sr as source
