# This is the first version of PHYS14 cuts, optimized on  PHYS14 samples. 
#
# The ID cuts below are optimized IDs for PHYS14 Scenario PU 20, bx 25ns
# The cut values are taken from the twiki:
#       https://twiki.cern.ch/twiki/bin/viewauth/CMS/CutBasedPhotonIdentificationRun2#PHYS14_selections_PU20_bunch_cro
#       (where they may not stay, if a newer version of cuts becomes available for these
#        conditions)
# See also the presentation explaining these working points (this will not change):
