Compute the remaining luminosity to be processed for a CRAB job

First of all get the JSON file containing the CRAB job part still to be processed :
crab -report -c XXX
Then, use your favourite LumiCalc instance to compute the integrated luminosity of this JSON list of events -i XXX/res/missingLumiSummary.json overview

Get the prescaling information on physics objects

If necessary, modify all occurences of constexpr to const in PhysicsTools/Utilities/interface/LumiReWeighting.h (C++11 feature not fully supported on Ingrid and LXPLUS)

Instructions on how to use LPAIR

First of all, fetch the latest revision of the CDF version of LPAIR on your favourite SLCx 32-bit machine

23rd-27th January

Created new EDAnalyzer ( GeneratePUdist) to generate the pileup distributions within a unique root file (using a TFileService) :

  • genPUdist
    • TNPVIcount : number of PileupInfo elements (should be 3 all the way)
    • TNVTX : number of reconstructed vertices within the event
    • TNPUTrue : number of true interactions (returned by getTrueNumInteractions() method)
    • TNPUInTime : number of interactions reconstructed in-time (returned by getPU_NumInteractions() method)
Modified the python config file (currently test/ If the previously mentioned root file is not discovered the analyzer will generate it using the EDAnalyzer. Otherwise, the next step will be performed : construction of the TTree using the GammaGammaMuE EDAnalyzer and weights evaluation for each event using the 3D reweighting package.

root files for pileup distributions on afs

As of today, the following files were available :

filename from run to run
Cert_160404-163869_7TeV_May10ReReco_Collisions11_JSON_v3.pileupTruth_v2_finebin.root 160404 163869

Cert_178098-180252_7TeV_PromptReco_Collisions11_JSON.pileupTruth_v2_finebin.root 178098 180252

Note that these are "true" distributions with fine binning size for Lumi3DReweighting as seen in PileupMCReweightingUtilities.
