Hi ,
thank you, Rene , for your reply.; it’s what I needed.
I have to make a fit now. How can I calculate the error on the RMS90?
Thank you very much

What do you want to do exactly? a fit with a gaussian? if yes, do
TF1 *g = new TF1("g","gaus",xmin,xmax);
myhisto.Fit(g,"NR");
double errorSigma = g->GetParError(2);
