    33 After the <header> and <init> blocks, the file essentially contains a list of event blocks, each of which begins with an opening <event> tag and ends with a corresponding </event> tag. There can be an arbitrary number of events in one file (depending on the input parameters of the simulation). The specific contents of the blocks will be described below. Note that the <header> and <init> blocks do not contain any relevant information in the current GiBUU implementation (and therefore can be ignored).

    5252 * 1: ID code of the particle (in [http://pdg.lbl.gov/2013/reviews/rpp2012-rev-monte-carlo-numbering.pdf PDG numbering scheme], which differs from our internal [wiki:ParticleIDs GiBUU numbering scheme]). This number determines the identity and charge of the particle.
     53 * 2-6: Unused (always 0).
    5354 * 7-9: 3-momentum (px, py, pz) of the particle in GeV. Usually the z-axis corresponds to the beam direction.
    5455 * 10: Energy E of the particle in GeV.
    5556 * 11: Mass m of the particle in GeV.
     57 * 12: Unused (0).
    5658 * 13: Spin of the particle ('9'=unknown).

    58 The other columns are not used in the current GiBUU implementation and therefore will be zero. The example event shown above contains a three-body final state, consisting of a proton, neutron and pi+ (produced in a pp collision).
