Hi All,
I am trying to add histograms(with same name) from different root files. I have looked at the example hadd.C. What I want is the following: before writing one particular final histogram which will be the sum of the histograms from different root files I would like to assign a different weight to each histogram.
h_final = 0.1*h_from_file1 + 0.4*h_from_file2 + 0.8*h_from_file3 ..etc.
Could someone tell me how can I do that.I couldn`t find this option in hadd.C
Thanks
Mansoora
