Is there any way to check if a bin in a THnSparse histogram is empty?
My full problem is the following:
I would like to GetBinContent from 3 out of the 11 dimensions in several THnSparse histograms and put it into a new 4 dimensional THnSparse histogram. As I cannot simply merge them and use a projection, I need to iterate through the bins and get the content to then set it in the new hist. However, if I use GetBinContent on an empty bin, it seem to return something non-zero.
Any help is immensely appreciated!
