Neutrino Oscillation Analysis of 217 Live Days of Daya Bay and 500 Live Days of RENO

Figure 3

Background-subtracted reconstructed positron prompt energy distributions for Daya Bay (a) and RENO (b). Black crosses are data; blue (red) line histograms show the MC expected no-oscillation (best fit) spectra. The background histograms are shown in magenta. See text for details. For Daya Bay, the distributions are absolutely normalized and account for the 5 MeV bump effect. For RENO, the predicted ND and FD distributions are normalized such that the best fit and data histograms have equal areas outside the 5 MeV bump region (). The bottom-right plot (RENO) compares the observed spectrum in the FD with no oscillation and the best-fit predictions obtained from the measurement at the ND, which account for the effect of the 5 MeV bump.
