ILDPerformance/pi0
===================

Test performance of pi0 / eta / eta' reconstruction
J.List, Nov 2015

needs:
- a physics sample (best with jets) to test (DST)
- insert path in scripts/pi0Tree.xml 
- if needed adjust collection names and/or name of output root tree 
- matching GEAR file (scripts/GearOutput.xml is ILD_o1_v05)
- if needed adjust links to weight files of IsolatedLeptonTagging
