class RooStats::HistFactory::Channel

This class encapsulates all information for the statistical interpretation of one experiment. It can be combined with other channels (e.g. for the combination of multiple experiments, or to constrain nuisance parameters with information obtained in a control region). A channel contains one or more samples which describe the contribution from different processes to this measurement.
