- Energy Range: 475 MeV - 3000 MeV reconstructed neutrino energy

- ntuple file of MiniBooNE sin
^{2}(2theta) sensitivity and upper limit curves as a function of Dm^{2}, for a 2-neutrino muon-to-electron antineutrino oscillation fit, and 90% and 3sigma confidence levels. The file contains 190 rows, one for each Dm^{2}value in the range 10^{-2}< Dm^{2}(eV^{2}) < 10^{2}, and 5 columns per row with the following format:

(Dm^{2} (eV^{2}), sin^{2}(2th)_{max, 90% CL}, sin^{2}(2th)_{max, 3sigma CL}, sin^{2}(2th)_{sens, 90% CL}, sin^{2}(2th)_{sens, 3sigma CL})

where sin^{2}(2th)_{max} and sin^{2}(2th)_{sens }indicate
the upper limit and sensitivity, respectively, and 90% and 3sigma CL
indicate the confidence levels corresponding to those numbers.

- ntuple file of MiniBooNE 2-dimensional chi2 surface as a function of ( Dm
^{2}, sin^{2}(2theta) ) in the range ( 10^{-2}< Dm^{2}(eV^{2}) < 10^{2}, 3·10^{-4 }< sin^{2}(2theta) < 1 ). The file contains 36,100 rows, one for each ( Dm^{2}, sin^{2}(2theta) ) pair of values, and 3 columns per row with the following format:

(Dm^{2} (eV^{2}), sin^{2}(2th), chi2)

Note: the value quoted in the third column is the total, and not the reduced, chi2 value (ie, it has not been divided by the number of degrees of freedom)

- Instructions on how to use this information can be found here.
- A FORTRAN program implementing these intructions to perform an example oscillation fit can be found here (note: you will need CERNLIB libraries, including LAPACK libraries, to build this program).
- Note: The above program calculates a signal prediction on an event-by-event basis, unlike the fit method employed in the official MiniBooNE oscillation analysis which uses a signal-averaging technique as a function of neutrino energy. The program will therefore yield slightly different (yet consistent) best-fit chi2 and oscillation parameters than those published by the MiniBooNE collaboration.
