Check here https://hypernews.cern.ch/HyperNews/CMS/get/jet-algorithms/399.html. In particular:

PF jet ID: For 2.7 < abs(eta) <= 3.0, the cut on number of neutral particles is now > 2 https://twiki.cern.ch/twiki/bin/viewauth/CMS/JetID#Recommendations_for_13_TeV_data
Pileup jet ID: A new training for 80X was integrated for the Fall16 data-rereco and Tranch4 MC production. It can be re-ran on any AOD/MiniAOD https://twiki.cern.ch/twiki/bin/view/CMS/PileupJetID#Information_for_13_TeV_data_anal

@degrutto @arizzi

I assume v25 will produced using the ReReco data and Moriond17 MC? This means the PU jet ID should already be up to date.

I will take care of updating the PF Jet ID once we moved to the new Heppy base.

PU JetID wp are read from this PhysicsTools/Heppy/python/physicsutils/PuJetIDWP.py that is hardcoded Heppy stuff... how can you be so sure that being ReReco we are ok??

arizzi commented 7 years ago

plus right now we actually take it from here vhbb_combined.py:JetAna.externalPuId="pileupJetIdUpdated:fullId" but removing this line rather than getting the puID from the file we get the hardcoded heppy stuff
