Measured prompt energy spectrum for each integration period (data points) superimposed on the expected prompt energy spectrum, including backgrounds (green region), for the no-oscillation (blue dotted curve) and best-fit (red solid curve) at sin²(2θ₁₃) = 0.109 and Δm² = 2.32×10⁻³ eV². Inset: stacked spectra of backgrounds. Bottom: differences between data and no-oscillation prediction (data points), and differences between best fit prediction and no-oscillation prediction (red curve). The orange band represents the systematic uncertainties on the best-fit prediction.

Text files containing the numerical values of the bin contents of each histogram in Figure 1 are given below. Note that bins cover two periods of data integration: two periods of 18 bins each, for 36 total bins. Bin populations are given in units of events per 0.5 MeV.

• Bin boundaries, in MeV: BinBoundaries.txt
• Binned IBD Candidate Data: DataVector.txt
• Best-fit signal: BestFit.txt
• Null-oscillation signal+background, with best-fit backgrounds: Unoscillated.txt
• Lithium-9 background at best-fit value: LithiumVector.txt
• Fast n and stopping muon background at best-fit value: FastNVector.txt
• Accidentals background: AccidentalVector.txt

Uncertainties on the signal and background predictions are represented using a covariance matrix. Matrices representing the systematic contributions from a number of sources are contained in the following ROOT-formatted file as TMatrixD objects. A total covariance matrix is also given. Details on the matrices are available in the README file accompanying the fitter package.

• Covariance Matrices: AbsoluteMatrices.root

The following materials can be used to reproduce the oscillation fit results. To use, unzip the archive file and follow instructions in the included README.
