The SBNEventWeight package calculates a set of weights attached to art events, including the BNB flux (an implementation based on the MiniBooNE flux model), GENIE interaction model systematics (using GENIE ReWeight via nutools), and additional systematic uncertainties (e.g. cross section ratio uncertainties due to second-class currents).

This package began from a clone of the larsim and ubsim EventWeight modules and calculators, for specialization to SBN systematics.

Authors: The EventWeight framework and calculators were initially developed by the MicroBooNE collaboration with contributions from Raquel Castillo Fernandez, Marco Del Tutto, Joseph Zennamo, Ariana Hackenburg, Adam Lister, Andy Mastbaum, Herb Greenlee, Kirsty Duffy, Steven Gardiner, Lauren Yates, and Wes Ketchum. The framework was ported into larsim by Marco Del Tutto. See individual weight calculators for additional author information.
