MET calculation
Created by: eleboulicaut
I'm creating this issue because I don't think we ever came to a conclusion about this.
I found that we get different results when calculating the MET from the negative sum of all truth non-neutrino particles in the event or from the truth neutrinos themselves.
I wrote a test script to show this in truth-studies/Kinematics/testMET.py
(here in branch dev_elise).
Below are the plots that are obtained with the script. I would expect "From truth neutrinos" to agree with "From neg sum of truth objects" or "From neg sum of truth objects incl rad". But it differs from both. Am I missing something?
