make JME way to identify pileup default by turning off following option in default sequence
checkClosestZVertex = cms.bool(False)

• not include charged hadrons as pileup if there is no vertex assoicated

@monttj I don't think this is sufficient. If you load

PhysicsTools/PatAlgos/test/patTuple_PF2PAT_cfg.py

and backtrack how

process.patJetsPFlow

are produced you will see that they still come from the 'JME' instance of pfNoPU.

okay, it has been changed all downstream of PFBRECO.
Since it shares with reco sequence (I believe so), we can stick to "JME" postfix for now not to make further confusion.

@monttj since #3510 has been merged, you can close this PR.

Hi Taejeong

Should I expect any changes in RECO objects or in the DQM plots?
If so, some notes would help

[ferencek]

@slava77 This PR can be closed. This was an attempt to modify some PFBRECO modules so that example PAT config files stay backward compatible. But as Taejeong pointed out, PFBRECO sequence is now also used in the standard reconstruction so it is easier to just update the PAT config files which was done in #3510

Hi Dinko,

Thanks for the comment.
I'm giving a -1 to take off the RECO list and Taejeong can then close it.

Hi Slava,

Sorry for being late.
I wanted to remove the postfix "JME" in PAT configuration.

It does not affect the reco with changes as reco uses "JME" which this issue was trying to make as default without postfix.

Hi Taejeong,

I'm confused.
Should this PR be reopened and considered for the release
or did you just provide more details to the comments from Dinko and this PR being closed is OK (because there is a different solution elsewhere)

Please clarify.
(if needs to be reopened, please reopen)

[monttj]

Hi Slava,

I tried to provide more details in addition to the comments from Dinko.
It does not need to be reopened for now.
