=== PdfInfo for SingleTopDPDMaker ===

PdfInfo or PdfTreeMaker is a tool that inserts PdfInfo using two different methods for mc08 and mc09.

'''mc09''': uses genEvt->pdf_info()

'''mc08''': as pdf_info not available, fall-back method fills first two partons (usually barcode 3 & 4) from TruthParticleContainer

==== variables ====

For the mc09 method five variables will be saved in the PdfTree:
{{{
  int m_id1;        // flavour code of first parton
  int m_id2;        // flavour code of second parton 
  double m_x1;      // fraction of beam momentum carried by first parton ("beam side") 
  double m_x2;      // fraction of beam momentum carried by second parton ("target side") 
  double m_scalePDF;  //  Q-scale used in evaluation of PDF's   (in GeV) 
}}}

For the mc08 method the kinematics and pdgId of the incoming partons are saved. px, py and pt should be zero. The number of partons should be two.
{{{
  std::vector<double>* m_InitialParton_px;
  std::vector<double>* m_InitialParton_py;
  std::vector<double>* m_InitialParton_pz;
  std::vector<double>* m_InitialParton_pt;
  std::vector<double>* m_InitialParton_e;
  std::vector<double>* m_InitialParton_pdgId;
  std::vector<double>* m_InitialParton_barcode;
  int m_InitialParton_N;
}}}

The following additions have to be made to the python files in the share directory:

runSingleTopDPDMaker.py:
{{{

}}}
