First look at the HCal MIP peak for production_FF_OO_200GeV_2021 data  with ECal open and HCal closed.
Idea is to select single hit cluster with no neighboring clusters and plot the energy distribution for each towers of HCal. 

Observation:
All towers have peak around 0.2GeV not around 1.5GeV where MIP is expected. May be this is coming from background. 

Next Step: 
Need to work on cuts to reduce the background.
Look at the ECal and HCal closed detector configuration.
