The following MiniBooNE information from the 2009 nuebar appearance paper is made available to the public:

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

• ntuple file  of MiniBooNE sin²(2theta) sensitivity and upper limit curves as a function of Dm², for a 2-neutrino muon-to-electron antineutrino oscillation fit, and 90% and 3sigma confidence levels. The file contains 190 rows, one for each Dm² value in the range 10^-2 < Dm² (eV²) < 10², and 5 columns per row with the following format: 

• 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 (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
• 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 
• ntuple file of 28,685 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

• Energy Range: 200 MeV - 3000 MeV reconstructed neutrino energy

Instructions

• 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.
