 Towards finalizing the large systematic uncertainty coming from the PID estimated using TPC only, I have now applied TPC and TOF together.
  Use of both detector helps to remove large fraction of proton and kaon background out pion signal region, To remove dominant proton and kaon background, 
  I applied polynomial cut using nSigmaTOFpion. The details of this PID approach and its impact on the results can be found in the attached sildes.
