Plugin that implements reweighting for additional pp interactions ("pile-up")
This plugin performs reweighting on pile-up based on the expected number of pile-up interactions, or the "true" simulated pile-up. The idea follows the official recipe [1].
Inputs needed for the reweighting are the target (data) distribution of pile-up (normally it is constructed with the help of script pileupCalc.py [2]), the pile-up profile used in simulation, and the desired systematic variation as described in [3]. It is possible to provide individual simulated profile for every process, although usually a common one would suffice.
This plugin exploits a PileUpReader with the default name "PileUp".

| PileUpWeight::PileUpWeight | ( | std::string const & | name, |
| std::string const & | dataPUFileName, | ||
| std::string const & | mcPUFileName, | ||
| double | systError | ||
| ) |
Creates a plugin with the given name.
Input arguments specify names of files containing distributions of "true" number of pile-up interactions in data and simulation. By default, provided file names are resolved with respect to directory data/PileUp/. The data file must contain a histogram named "pileup" that describes the distribution. The file with profiles in simulation may contain individual distributions for some or all processes (named according to labels returned by method Dataset::GetSourceDatasetID), and, in addition to them, it must include the default distribution named "nominal". Input histograms with arbitrary normalization and binning (including variable one) are supported.
The last argument sets desired systematical variation as defined in [1]. [1] https://twiki.cern.ch/twiki/bin/view/CMS/PileupSystematicErrors
