0. The simple LXe Monte Carlo (4850 level) with isotropic angular distribution on a sphere (Monica)
1.“Groom” Parametrization of muons at Homestake depth, propagated through rock using GEANT4 v4.9.3 P02 with new mu-nuclear to produce neutrons and all secondaries. Assumes Soudan rock and a flat overburden, but has a good angular distribution of incoming neutrons.
2. Best Model: Homestake MUSUN Muons + GEANT4, taking account of the geography and geology of the Homestake site prepared by Chao and Angie. Muons are then propagated through rock using GEANT4 v4.9.5 to produce neutrons and all secondaries.
3. Homestake MUSUN Muons + FLUKA: Muons generated via MUSUN, but then propagated through the rock via FLUKA (Raul and Angie)
4. Neutron Parameterization : Muons generated via MUSUN, but then creating a Neutron parametrization instead of all secondaries (Chao)
5. Soudan MUSUN Muons + GEANT4: Muons generated via MUSUN, taking account of the geography and geology of the Soudan site. Muons then propagated through rock using GEANT4 v4.9.3 P02 with new mu-nuclear to produce neutrons and all secondaries. (Angie and Melinda)
6. The Neutron Multiplicity Meter (2100 mwe) with cosnθ distribution (partly derived from existing flux measurements)
