PFlow reconstruction in Heavy-Ions conditions

Sebastian Tapia Araya requested to merge stapiaar/athena:HIpflow_dev into 23.0

This MR has the purpose of providing the right inputs to PFlow algorithm under Heavy-Ion reconstruction conditions

In HeavyIon mode of reco, we name the calorimeter objects differently once we apply the energy subtraction, e.g. "AllCalo" --> "SubtractedCells", "CaloCalTopoClusters" --> "SubtractedCaloCalTopoClusters".. and so on

So far I have seen two places where calorimeter objects are read in the PFlow context:

  • PFCfg.py#0350, here cells key is provided through the "Egamma.Keys" then is updated automatically when Heavy-Ion egamma is ON, no change needed.
  • PFCfg.py#0420, here "CaloTopoClusters" and "CaloCalTopoClusters" are read. --> Adding functionality to read SubtractedCaloTopoCluster when HImode reco is ON

@mhodgkin would like to comment on this?

Is there any other place you think we should check that the inputs are right?

Also tagging HI people interested in PFlow and conveners, @mrybar @qhu @dhangal @angerami For reconstruction @jdandoy @christos
