Detailed Description

Customization functions for cmsDriver to get neutral weighted isolation

Function Documentation

def customizeDeltaBetaWeights_cfi.customize (   process) 
run neutral particle weighting sequence and use it for isolation of electrons, muons and photons

   syntax: --customise RecoParticleFlow/Configuration/customizeDeltaBetaWeights_cfi.customize
   It will add 2 new sequences to the RECO sequence that will produce pfWeightedPhotons and 
   pfWeightedNeutralHadrons. They are produced from pfAllPhotons and pfAllNeutralHadrons by rescaling
   pt of each particle by a weight that reflects the probability that it is from pileup. The formula is
   w = sumNPU/(sumNPU+sumPU). The sums are running over all charged particles from the PV (NPU) or from the PU.
   The function used in the sum is ln(pt(i)/deltaR(i,j)) where i is neutral particle that is being weighted and j
   is the charged particle (either PU or NPU) that is used to access 'pileupility' of a particle.

   Neutral isolation of electrons, muons and photons is calculated using the weighed collection.
