#
# This code produces at set of validation plots for a given detector card. 
#
# In order to run this you need to compile Delphes with Pythia8 first, see: 
# 
# https://cp3.irmp.ucl.ac.be/projects/delphes/wiki/WorkBook/Pythia8
#
# After you (re-)compiled Delphes with Pythia8 you are ready to go, execute from Delphes main dir:
#
# ./examples/validation.sh [detector_card] [number_of_events] 
# 
#  e.g.
# 
# ./examples/validation.sh cards/delphes_card_CMS.tcl 100000
#
# Note that the more events you specify, the more accurate the controls plots will be ...
# This said, 500k events should be ok for most cases.
