An excess of $20.9 \\pm 14.0$ events is observed in the energy range $475<E_\\nu^{QE}<1250$ MeV, which, when constrained by the observed $\\bar \\nu_\\mu$ events, has a probability for consistency with the background-only hypothesis of 0.5\\%. On the other hand, fitting for $\\bar{\\nu}_{\\mu}\\rightarrow\\bar{\\nu}_e$ oscillations, the best-fit point has a $\\chi^2$-probability of 8.7\\%.
