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/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_)
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]
InActive (bool): whether an interaction happened in active volume' this requires an interaction vertex (e.g. cosmic rays are out)

Member Function Documentation

void EventInfoTree::assignEvent ( EventInfo_t const & info )

Fills the information of the specified event.

Parameters

info	event information to fill the tree with
inPlots	whether this event is plotted (as opposed to filtered out)
