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. The list of hits is stored as an association.
|
| SpacePoint |
lardata/RecoBase |
Space point formed by combining hits from different planes. Hits stored as association.
|
| Track |
lardata/RecoBase |
Trajectory with momentum.
|
| PFParticle |
lardata/RecoBase |
Reconstructed particle? Association to track.
|
| 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.
