Move DiTauLowPt collection to LCTopo seed and add cluster info
As start of the unification of the DiTau high/low pt collections, move the low pt collection to be seeded by LCTopo LargeR jet instead of EMPFlow LargeR jet. Performance studies about different seeds are available in: https://indico.cern.ch/event/1424484/contributions/5993366/attachments/2872386/5029313/workflow%20plan%20full%20statistics.pdf showing the advantage of LCTopo over PFlow seed.
Additionally, since it's not possible to save clusters directly for TauID training studies, decorate DiTau object with "f_core" variable extracted from cluster information. The impact of this additional variable was evaluated running PHYS derivation over 1000 events in MC and Data and results of checkxAOD output are attached:
checkxAOD_PHYS_mc_unchanged.txt
checkxAOD_PHYS_data_unchanged.txt
checkxAOD_PHYS_data_changed.txt
-> the overall increase in size is at per mille level, so almost negligible
Tagging @ntamir , @oasulin , @davannic and @martindl for TauCP
Tagging also AMG and derivation coordinators @ekourlit , @gwatts and @emmat
Note: no changes for xAOD content, only in DxAOD
