August 8th

VPlusJetsAnalyzers is now on GitHub !

Owners have full access to all repositories and admin rights to the organization.

View team: https://github.com/organizations/VPlusJetsAnalyzers/teams/456421

And finally at long last we also have a github repository under cms-analysis!!
https://github.com/cms-analysis/ElectroWeakAnalysis-VPlusJets

(sigh) Well, we are gonna use the former.

Updated unfolding recipe from Nhan Tran

Documentation: http://arxiv.org/abs/1105.1160
http://hepunx.rl.ac.uk/~adye/software/unfold/RooUnfold.html

Code is here:
http://cmssw.cvs.cern.ch/cgi-bin/cmssw.cgi/UserCode/ntran/ElectroWeakAnalysis/VPlusJets/test/analyze/PlotterClass.py?revision=1.1&view=markup

Look here: 
    def doUnfolding( self, hResponse_input, hMeas_input, hTrue_input, hData_input ):

        hResponse = hResponse_input
        hTrue = hTrue_input
        hMeas = hMeas_input
        hData = hData_input
        response = RooUnfoldResponse( hMeas, hTrue, hResponse, hMeas.GetName(), hMeas.GetTitle() )

        unfold= RooUnfoldBayes     (response, hData, 4);    #  OR
        # unfold= RooUnfoldSvd     (response, hMeas, 20);   #  OR
        # unfold= RooUnfoldTUnfold (response, hMeas);

        hReco= unfold.Hreco();
        return hReco;
You also need: 
ROOT.gSystem.Load('RooUnfold-1.1.1/libRooUnfold.so')
from ROOT import RooUnfoldResponse
from ROOT import RooUnfold
from ROOT import RooUnfoldBayes
Directory example: 
/uscms_data/d2/ntran/physics/VJets/tlbsmPatTuples/v10_v6/CMSSW_4_2_8/src/ElectroWeakAnalysis/VPlusJets/test/analyze/RooUnfold-1.1.1
