###How to use this code for SL16d production:

# Load StRefMultCorr library
# NOTE: Add this line in your 'macro', not in the source code
gSystem->Load("StRefMultCorr");
# For grefmult
StRefMultCorr* grefmultCorrUtil = CentralityMaker::instance()->getgRefMultCorr_P16id() ;
grefmultCorrUtil->init(15075008);
grefmultCorrUtil->setVzForWeight(6, -6.0, 6.0);
grefmultCorrUtil->readScaleForWeight("StRoot/StRefMultCorr/macros/weight_grefmult_vpd30_vpd5_Run14_P16id.txt");

# NOTE: Add this line inside the source code
grefmultCorrUtil->initEvent(grefmult, vz, zdcCoincidenceRate) ;
# see StRefMultCorr.h for the definition of centrality bins
# Centrality from grefmult
const Int_t cent16_grefmult = grefmultCorrUtil->getCentralityBin16() ;
const Int_t cent9_grefmult  = grefmultCorrUtil->getCentralityBin9() ;
# Re-weighting corrections for peripheral bins
const Double_t reweight_grefmult = grefmultCorrUtil->getWeight() ;
# Corrected refmult (with z-vertex dependent correction and luminositiy correction)
# NOTE: type should be double or float, not integer
const Double_t grefmultCor = grefmultCorrUtil->getRefMultCorr() ;
