Evaluate a transfer function on Pt described by a 2D histogram retrieved from a ROOT file. More...
Detailed Description
Evaluate a transfer function on Pt described by a 2D histogram retrieved from a ROOT file.
This module takes as inputs two LorentzVectors: a 'gen-level' particle (which may be computed using for instance a Block or a 'real' transfer function) and a 'reco-level' particle (experimentally reconstructed). Assuming the LorentzVectors differ only by their Pt, this module returns the value of a transfer function (TF) evaluated on their respective Pt.
The transfer function (TF) is described by a 2D histogram (a ROOT TH2), where the X-axis defines the "generated" (true) Pt \(P_T_{gen}\), and the Y-axis the difference between the reconstructed and the generated Pt ( \(P_T_{rec}-P_T_{gen}\)).
It is assumed the TF is correctly normalised, i.e. integrals of slices along the Y-axis sum up to 1.
Integration dimension
This module requires 0 phase-space points.

Main function.
This method is called for each integration step. The module's logic and work happen here.
You'll usually want to override this function if you want your module to perform some task.
