// -*- C++ -*-
// Dec 2015 : Added bool m_cosmic to choose cosmic or collision run through python file

//integrate the code with some 8_0_X or 7_6_X recent IB and run the 
// following tests: 4.22, 8.0, 25.0, 140.53. You can always activate them using
//runTheMatrix.py -l 4.22

// 7th Nov 2015 :  tmpHOCalib.ecal03 = iso05.sumPt; // iso03.emEt+muonenr.em;
//                   tmpHOCalib.inslumi=lumiScale->begin()->pileup();
//
// April 2015 : Remove all digi part
//  Also look for HO geometry in CMSSW in parallel with stanalone one.
// Official one has problem in reco geometry, particularly tiles at the edge of wheel
// Remove all histogrammes except occupancy one 
// Remove Trigger bits
// But addition of these variables, ilumi (analyser), inslumi (analyser), nprim

// Feb09 2009
// Move the initialisation of SteppingHelixPropagator from ::beginJob() to ::produce()
//
// Oct3 2008
// Difference in tag V00-02-45 with previous code

// 1. One new object on data format, which was realised in  
//     CRUZET data analysis.
//2.  Remove all histogram and cout in the code
//3. An upgrade in code, which increases the acceptance of 
//    muon near the edge (this also realised in CRUZET data).
// Difference in wrt V00-02-45
// 1. initialisation tmpHOCalib.htime = -1000;
// 2. By mistake HLT was commented out
