Neutron Multiplicity toolchain

[mnieslony]

Three main new tools have been added:

• SimpleReconstruction: simple MRD-reconstruction based muon vertex and energy reconstruction by backpropagation of muon track into the water tank
• FindNeutrons: Find neutron candidates with simple cuts, add them to the Particles vector in the ANNIEEvent
• NeutronMultiplicity: Combine muon and neutron information into neutron multiplicity related plots.

The ClusterClassifiers tool now also forwards the cluster total PE, cluster time, and cluster nhits. It also tags the prompt muon by looking for the cluster with the highest charge in the prompt window.

The EventSelector tool can now also filter for events with good beam condition and for events with extended readout windows.

Added EventOffset variable to LoadGenieEvent in case the genie file match is done in the config file.

NeutronMultiplicity toolchains have been added in configfiles/NeutronMultiplicity, alongside helpful bash scripts to run over many files.

More information on the additions & concepts of the tools in docDB entry 5224.

Hi Michael, just a question for the SimpleReconstruction Tool: what are the units for the vertices?

[mnieslony]

Hi James, the units for the vertices should all be in meters. They are calculated in the standard ANNIE coordinate system centered in the center of the FMV, corresponding to a central water tank position of r_center ~ (0m, -0.144m, 1.681m).

I'm not gonna let it hold this up as it's not particularly important, but the TGraphs constructed in NeutronMultiplicity::InitialiseHistograms should probably be cleaned up manually. The Histograms may not need manual cleanup as they may get owned by the file, but TGraphs by default don't.
