I’d like to know if there is a way to do an average of 2 histograms . in bin i, let the value be v_i and the error dv_i.
Is there any function
TH1::Average(const TH1* h) that calculates for each bin the average :
v_i = (v_i / dv_i^2 + h->v_i / (h->dv_i)^2) / (1/dv_i^2 + 1/(h->dv_i)^2) );
dv_i = 1 / sqrt ( 1/dv_i^2 + 1/(h->dv_i)^2 )
? If this function does not exist, could it be implemented ?
