# This is the first round of Spring15 50ns cuts, optimized on  Spring15 50ns samples. 
#
# The ID cuts below are optimized IDs for Spring15 Scenario with 50ns bunch spacing
# The cut values are taken from the twiki:
#       https://twiki.cern.ch/twiki/bin/view/CMS/CutBasedElectronIdentificationRun2
#       (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):
#        https://indico.cern.ch/event/369245/contribution/2/attachments/1153005/1655984/Rami_eleCB_ID_50ns_V2.pdf
# NOTE: this V2 version is different from the V1 version for these conditions only
# by the cuts of the WP Tight for the barrel. All other WP and endcap are the same as V1.
# The changes was needed to make the WP Tight EB tighter than the HLT. For reference, the full V1 talk is here:
