Detailed Description

Flag tau candidates reconstructed near dead ECAL channels, in order to reduce e -> tau fakes not rejected by anti-e MVA discriminator

The motivation for this flag is this presentation: https://indico.cern.ch/getFile.py/access?contribId=0&resId=0&materialId=slides&confId=177223
