Hi,

thanks, very good hint, I didn't know that class

As far as I can see at the moment, only 1dimensional histograms are allowed. Is this true? Furthermore I haven't seen Projection-Methods. Or is it possible to obtain the calculated histogram object?

Unfortunately, a lot of methods, that are common for usual histograms like "Rebin" or "Projection" will not work, as e.g. the rebinning of the efficiency-histogram is something different than rebinning the nominator- and denominator and the dividing again.
