# In this file we define the locations of the MVA weights, cuts on the MVA values
# for specific working points, and configure those cuts in VID
#

#
# The following MVA is derived for PHYS14 MC samples for non-triggering electrons.
# See more documentation in this presentation:
#     https://indico.cern.ch/event/367861/contribution/1/material/slides/0.pdf
#

# This MVA implementation class name
mvaPhys14NonTrigClassName = "ElectronMVAEstimatorRun2Phys14NonTrig"
# The tag is an extra string attached to the names of the products
# such as ValueMaps that needs to distinguish cases when the same MVA estimator
# class is used with different tuning/weights
mvaTag = "25nsV1"

# There are 6 categories in this MVA. They have to be configured in this strict order
# (cuts and weight files order):
#   0   EB1 (eta<0.8)  pt 5-10 GeV
#   1   EB2 (eta>=0.8) pt 5-10 GeV
#   2   EE             pt 5-10 GeV
#   3   EB1 (eta<0.8)  pt 10-inf GeV
#   4   EB2 (eta>=0.8) pt 10-inf GeV
#   5   EE             pt 10-inf GeV
