  //Macro to run pi0 calibration on local ESD files.
  //Author: Boris Polishchuk.
  

  //Uncomment the line below if your ESD files are from old productions
  //so there are no PHOS geometry matrices written in the ESD.
  //You can find an ideal geometry here: $ALICE_ROOT/test/QA/geometry.root
  //and copy to your working directory.

  //AliGeomManager::LoadGeometry("geometry.root");

  //You can apply misalignment by following
  //(remember that your local OCDB in ./PHOS should contain a copy of the
  //$ALICE_ROOT/OCDB/PHOS/Align directory while ./PHOS/Calib/EmcGainPedestals
  //should contain the corrections to the calibration coefficients (~1) 
  //instead of real CC (~0.005)! ):

//   AliCDBManager::Instance()->SetDefaultStorage("local://$ALICE_ROOT/OCDB");
//   AliCDBManager::Instance()->SetSpecificStorage("PHOS/*","local://./");

//   AliCDBManager::Instance()->SetRun(0);
//   AliCDBEntry* e = AliCDBManager::Instance()->Get("PHOS/Align/Data");
//   TClonesArray *array = (TClonesArray*) e->GetObject();
//   AliGeomManager::ApplyAlignObjsToGeom(*array);
