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.

Monte Carlo Production for 35 ton
The above data model is used for the MC (Monte Carlo) samples produced for the 35-ton prototype detector. Five different reconstruction paths are followed: standard reconstruction, full cheat that makes extensive use of MC information, half-cheat that uses MC only to resolve TPC ambiguities. In addition, Pandora is run in standard and half-cheat modes.
