CMSSW_80X_v12_patch1

The producers introduced in v12 for MC have side effects on the data. Data is not analyzed because the collections required by new producers are not available in data therefore all data events are skipped.

CMSSW_80X_v11

Different treatment of low p_T & high eta genParticles

Main changes:

• Don't apply p_T/eta cuts on particles with status 1 (stable) or status 21-29 (from hard scattering, before radiation) particles
• Keep all copies of genParticle top quarks

Copies of quarks were not saved if they have p_T < 15 GeV. This causes problems for the top quark, where e.g. the copy with status 62 is used for calculating the top pt reweighting systematic uncertainty.

CMSSW_80X_v9

slimmed mets mueg cleaned collection fixed for data, no change for MC

CMSSW_80X_v7

Adding slimmedMETsMuEGClean for reminiAOD data

CMSSW_80X_v1

First stable version of 80X

Missing: event cleaning for bad PF muon and bad charged particle

CMSSW_76X_v3

With the right isolation for the leptons

CMSSW_76X_v2

Updated MET filters & genParticles

V5_0_5

Production Release

This contains PAT recipe up to this point.
https://twiki.cern.ch/twiki/bin/view/CMSPublic/SWGuidePATReleaseNotes52X#New_muon_selectors

This release version has photon object in top tree.

V5_0_4

1. fix variable type in Muon and Electron class
2. add TRootPhoton and PhotonAnalyzer
3. add .gitignore file
4. remove b-tag scale factor from DB
5. add basic selections, photon isolation for charged hadron, pileup charged hadron, neutral hadron and photon
6. remove Hcal noise filter for both full and fast sim for the time being
7. add output collections in PAT for photons in order to produce top-tree from PAT.

V5_0_3

1. modify PAT_cfg.py and PAT2TOPTREE_cfg.py so that it can run over FAST SIM sample to produce TOPTREE.
2. event cleaning sequence runs also for MC by default (TJ: I think it should run for both data and MC even though the event cleaning will do almost nothing for MC)
