Blue is completely done
Red is high priority
Orange is lower priority: need by end of study
Grey is lowest priority-- should do eventually

Energy in the detector is the total energy an electron would have (i.e. including rest mass energy of an electron). For LAr, we assume gammas are visible and they are included in the interaction product energy.
Event rate calculations using GLoBES front end.
The fluxes are in neutrinos per cm^2 per 0.2 MeV bin per time interval.
Green: sum of numu, nutau, numubar, nutaubar; Red: nue; Black: nuebar
Event rate plots are for SK1 parameters, 100 kton mass. They show events per 0.5 MeV bin.
Solid (left): events detected per neutrino energy.
Dashed(right): events per detected energy, after energy smearing and efficiency. This is the distribution that would be observed. (Smearing in GLoBES includes product distribution and detector resolution.)
Black: IBD; Red: elastic scattering, all flavors; Green: nue on 16-O;Blue: nuebar on 16-O; Cyan: NC excitation events on 16-O, sum of all; Magenta: total
These plots are for Jim Kneller's flux file, integrated over the full time interval:
