/*
  The reconstruction parameters are used in the AliTPCclustererMI and AliTPCtrackerMI
  
  They are retrieved:
  0. User speciefied it in reconstruction macro
  1. if (not 0) from OCDB  - AliTPCcalibDB::GetRecoParam(eventtype)
  2. if (not 0 or 1) default parameter - High flux enevironment used  

  FIXME:
  In the future  reconstruction parameters should be changed on event basis
  But for the moment, event types are still not defined 


  // Setting for systematic errors addition
  [0] - systematic RMSY
  [1] - systematic RMSZ
  [2] - systematic RMSSNP
  [3] - systematic RMSTheta
  [4] - systematic RMSCuravture -  systematic error in 1/cm not in 1/pt
  //
  //  How to add it example - 3 mm systematic error y, 3 cm systematic error z (drift)
  Double_t sysError[5]={0.3,3, 0.3/150., 3./150.,0.3/(150*150.)}
