Switching to default HCAL Reco in 73X

[bachtis]

After discussion with HCAL DPG flipping PF to default reconstruction(Method I)
Will commit again when Method II is ready to apply timing cuts.

A new Pull Request was created by @bachtis for CMSSW_7_3_X.

Switching to default HCAL Reco in 73X

It involves the following packages:

RecoParticleFlow/PFClusterProducer

My understanding was that Method 2 is comping imminently and is expected to become the default for HCAL.
If that would apply for PF reco, I don't see an immediate reason for this PR.

[bachtis]

Still until this is done HCAL DPG asked to have Method I as the default while now we have Method 1.5 in

[slava77]

OK.
Do you have any comparison plots to document the changes based on relevant performance plots?
Please post a few, if you have them.

@cmsbuild please run tests

@bachtis
Michalis, do you have any performance plots showing this change makes things better (or not worse)?

Comparisons of this PR with with the current baseline (I'm using CMSSW_7_3_X_2014-10-30-0200 + #6103 for the baseline, and add this PR+enabling method 2). The conclusions are somewhat similar to what I had before: there is a fairly large increase in the number of pf neutral hadrons at low momenta, the absolute response in jets decreases slightly at the highest end of the spectrum.

Other distributions are fairly similar with the current RECO in the release.

So @slava77 , you mean this is method 2 vs method 1.5 right ? I assume "what we had in the release" is 72X?

Hi Michalis,
Could you please redo your commits on top of #6150
or, maybe simpler, keep just commits in the PF
