Definition at line 1575 of file LauSimpleFitModel.cc.

void LauSimpleFitModel::appendBinCentres ( LauFitDataTree * inputData )

protected

We'll be caching the DP amplitudes and efficiencies of the centres of the true bins. To do so, we attach some fake points at the end of inputData, the number of the entry minus the total number of events corresponding to the number of the histogram for that given true bin in the LauScfMap object. (What this means is that when Laura is provided with the LauScfMap object by the user, it's the latter who has to make sure that it contains the right number of histograms and in exactly the right order!)
