This just adds a very basic PFlow algorithm that takes the PFlow inputs (configured mainly by the jet slice) and performs the standard 2-vector sum over them. The algorithm saves 3 components
NeutralPFOs: the sum over all neutral PFlow objects
ChargedHSPFOs: the sum over all charged PFlow objects associated to the primary vertex
ChargedPUPFOs: the sum over all charged PFlow objects not associated to the primary vertex
By default, the final MET value is just
ChargedPUPFOs can be included if
ChargedOnlyFromPV = false, but this currently has no way of setting it from the trigger name.
reco_alg value for this trigger is
pfsum and there are no further configurations it can take, so the output container name is
HLT_MET_pfsum, which I have added to the EDM lists.
LS2_v1 to make sure it runs correctly with other chains (especially the existing jet PFlow chains) and it appears to run fine, so I've included updated references for the relevant tests. I've also changed the
slice_met test to have
forceEnableAllChains=True so that we get actual stats in the chains seeded from L1_XE10.
I originally pushed this with the algorithm name
pf, but I realised that I also wanted to configure a PFlow version of
mht_pf to be consistent with the jet slice's approach. This however would have required
pf to appear as both a
recoAlg key and something else, which isn't allowed, so I renamed
