Detailed Description

Class managing the serialization of event information in a simple ROOT tree.

The tree is supplied by the caller. This object will create the proper branches into the tree and assign addresses to them. Then it will assume they will stay assigned.

On assignEvent(), the branch addresses are assigned the values from the event information. The tree is not Fill()-ed.

The tree structure is: CC/i:NC/i:IntType/I:Time/D:NuE/D:OutLeptE/D:TotE/D:SpillE/D:InActive/O, with a single branch per element.

Branches:

CC (unsigned integer): number of neutrino CC interactions in the event
NC (unsigned integer): number of neutrino NC interactions in the event
IntType (integer): code of interaction type (see simb::int_type_)
Time (double): time of the interaction in simulation time scale
NuE (double): energy of the generated initial state neutrino [GeV]
OutLeptE (double): energy of the generated final state lepton [GeV]
TotE (double): total deposited energy in the event [GeV]
SpillE (double): total deposited energy during the beam gate [GeV]
PreSpillE (double): total deposited energy during the pre-spill window [GeV]
ActiveE (double): energy deposited in active volume [GeV]
SpillActiveE (double): energy deposited in active volume during the beam gate [GeV]
PreSpillActiveE (double): energy deposited in active volume during the pre-spill window [GeV]
InActive (bool): whether an interaction happened in active volume' this requires an interaction vertex (e.g. cosmic rays are out)
NVertices (unsigned integer): number of interaction vertices in event
Vertices_ (list of points): the location of all the interaction vertices in the event; it's a vector of GenVector 3D points (can access coordinates as Vertices.X() or Vertices.fCoordinates.fX)
