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 without use of MC, with full cheat that makes extensive use of MC information and half-cheat that uses MC only to resolve TPC ambiguities. In addition, Pandora is run in standard and half-cheat modes. The following table lists the names of the producers for these reconstruction paths and the types of data products they produce. The name and type can be used to retrieve each data product.
