Updates after PWG-HF approval

revised systematic uncertainty

• the reason of the mean < 1: most of trials were applied tighter cuts on lower cut (nSigma<-1) due to avoiding hadron contamination
• recalculated the uncertainty by taking value nSigna<-1
  • now the mean is almost 1
• apply 2% uncertainty in all pT
  • possibly apply 1% at low pT, but don't much final uncertainty

fixed error calculation of photonic electron reconstruction efficiency

uncertainty from different pT shape of parent

• uncertainty from different parent weight (pi0 and eta) for efficiency (pair finding) calculation
• add pT dependent uncertainty (red curve)

Comparison with models

• NOTE: uncertainty from photonic electron due to different pT weight in the efficiencies are not't implemented
