- Antineutrino mode fit in 200 MeV - 3000 MeV reconstructed neutrino energy range

- 90% sensitivity contour, 1 sigma limit contour, 90% limit contour and 99% limit contour. Sensitivity and limit curves for a 2-neutrino muon-to-electron antineutrino oscillation fit. Only anti-neutrinos were assumed to oscillate. Frequentist studies were performed to determine the proper coverage. Each file contains a set of (sin
^{2}(2theta), Dm^{2}) points on a given contour. - ntuple file of MiniBooNE 2-dimensional likelihood 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), -2ln(L)) - ntuple file of MiniBooNE 2-dimensional effective chi2 surface (for 2 degrees of freedom) reproducing the contours corrected with frequentist studies given above. The effective chi2 is calculated using the likelihood surface above and frequentist studies at a given (sin
^{2}(2theta), Dm^{2}) point. An approximation was used for points where frequentist studies were not performed. In particular, frequentist studies were not performed at all of the points outside of 99% limit contour. 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)

- 1D array of bin boundaries in electron antineutrino reconstructed neutrino energy
- 1D array of observed electron antineutrino candidate events per reconstructed neutrino energy bin
- 1D array of observed muon antineutrino charged-current quasi-elastic (CCQE) candidate events as a function of reconstructed neutrino energy (same file as one for default energy range; note: not the same bin boundaries as electron antineutrino candidate events)
- 1D array of predicted background electron antineutrino candidate events per reconstructed neutrino energy bin
- 1D array of predicted muon antineutrino CCQE candidate events per reconstructed neutrino energy bin
- muon-to-electron antineutrino full transmutation
- 2D array of fractional covariance matrix for muon-to-electron antineutrino full transmutation events, predicted electron antineutrino background events, and predicted muon antineutrino CCQE events (three side-by-side diagonal blocks) per reconstructed neutrino energy bin, including systematic uncertainties for all three samples, and statistical uncertainty for the predicted electron antineutrino background and predicted muon antineutrino CCQE events. Note that this matrix is not exactly the same as the antineutrino sub-block of the combined matrix. Only antineutrino events are used here for the full transmutations part of the matrix. Secondly, more MC variations were used to build this matrix.
- ntuple file of 86,403 predicted muon-to-electron antineutrino full transmutation events, containing information on reconstructed neutrino energy, true neutrino energy, neutrino baseline, and event weight for each event.
