Detailed Description

Filter to select events with deviation from nominal total kinematics smaller than a tolerance parameter.

This filter adds up the momenta of all generated particles (except the initial state protons) and requires that the sum of the of the three-momenta is zero (within tolerance) and that the sum of the energies is equal to the center of mass energy (within tolerance). The center of mass energy is obtained from the initial state protons. The tolerance is specified in GeV.
