Enable FlowElement reconstruction by default for PFlow
This sets the flag enabling FlowElement
reconstruction to True
by default, meaning these will always be reconstructed alongside the "old" PFO
EDM unless the user manually turns the flag off.
This adds three new FlowElement
collections to default xAOD content. I've checked the size impact on a small handful of JZ2 (multijet) events which I reconstructed from RDO:
-
JetETMissNeutralFlowElements
: 56 kb/evt -
JetETMissChargedFlowElements
: 14 kb/evt -
JetETMissLCNeutralFlowElements
: 10 kb/evt
This translates to a 15-20% increase in the total file size on disk. Note that this is temporary, until early 2021: once we've finished validation for all FlowElement
usage we'll remove the old PFO
collections these are replacing, reducing the file sizes back to how they are now (the sizes of the FE and PFO collections are very similar).
Tagging @sawyer, @cdelitzs, @mswiatlo, @delsart, @mhodgkin, @goetz for their information and any input they have.
Tagging also @miochoa & @jferrand as this is relevant for PhysVal with Jet/MET. With this, any new AOD reconstructed with default settings will be usable for our FlowElement validation.
