• nChannels defines the number of independent channels. This must be greater than zero.
• nSubChannels defines the number of independent subchannels. This must be greater than or equal to zero.
• nBins is the number of histogram bins. It must be at least one. In many cases it makes sense to choose values between 10 and 20. The two special bins for values that lie below fMinBinned or above fMaxBinned are not included in this value.
• fMinBinned is the lower limit value for which samples are counted in the regular histogram bins.
• fMaxBinned is the upper limit value for which samples are counted in the regular histogram bins. fMaxBinned must be greater than fMinBinned.
