TWO-DIMENSIONAL BACKGROUND ESTIMATION FUNCTION // This function calculates the background spectrum in the input histogram h.
The background is returned as a histogram.
Function parameters: -h: input 2-d histogram -numberIterations, (default value = 20) Increasing numberIterations make the result smoother and lower. -option: may contain one of the following options
NOTE that the background is only evaluated in the current range of h. ie, if h has a bin range (set via h->GetXaxis()->SetRange(binmin,binmax), the returned histogram will be created with the same number of bins as the input histogram h, but only bins from binmin to binmax will be filled with the estimated background. //
