Dear developpers,

If I am creating a TH1F histo (here h2) from the following TTree Read/Draw sequence:  

T2.ReadFile("fluxPosCazes_Globes.dat","sene/F:snue:snumu:snutau:sanue:sanumu:sanutau");   T2.Draw("sene>>h2(501,0.0,10.04)","snumu");

(nb: T2 has 501 entries as I have checked from T2.Print())

What is the content of #entries of h2 and the result of the mean/sigma value?

Cheers
Jean-Eric
