LBNE Far Detector Software Data Model

This page documents D. Adams attempts to understand the LBNE EDM (event data model), i.e. the classes describing the data share by modules via the event data store and written to event data files.

Simulation

The following table lists the EDM classes used in the simulation.

Class	Location	Description
MCTruth	nutools/SimulationBase	ID, PDG ID, status code and starting and ending position and momentum for each input MC particle
MCParticle	nutools/SimulationBase	ID, PDG ID, status code and starting and ending positions and momenta for each MC particle
SimChannel	larsim/Simulation	Energy deposited by each MC particle in the volume for each readout channel

Reconstruction

The following table lists the EDM classes used in the reconstruction.

Class	Location	Description
RawDigit	lardata/RawData	Raw (convoluted) ADC signals in time slices. Unpack with raw::Decompress in RawData/raw.h
Wire	lardata/RecoBase	Deconvoluted signal for each channel.
Hit	lardata/RecoBase	Peaks on wire signals.
Cluster	lardata/RecoBase	Associated hits in a TPC plane, i.e. 2D tracks. Association to hit.
SpacePoint	lardata/RecoBase	Space point formed by combining hits from different planes. Association to hit.
Track	lardata/RecoBase	Trajectory with momentum. Association to space point, hit, cluster
PFParticle	lardata/RecoBase	Reconstructed particle? Association to cluster, space point, track, seed, vertex.
Seed	lardata/RecoBase	Space point with direction. Used by Pandora.
Vertex	lardata/RecoBase	Vertex position. Association with PFParticle. Used by Pandora.

Plans to update the reconstruction model are described in a talk by Gianluca.
