 | The significance with which the $\theta_{23}$ octant can be resolved as a function of the true value of $\sin^2\theta_{23}$, for exposures of seven (green) or 10 (orange) years, assuming the staging scenario described in table~\ref{table:dune_staging_scenario}. The inputs to the sensitivities are shown in Fig.~\ref{fig:dune_fd_samples}. The neutrino oscillation parameters are based on NuFit~2016~\cite{Esteban2017}. The width of the band represents the range in sensitivity due to variation in the true value of $\delta_{\textrm{CP}}$, where the band covers the top 80\% least extreme sensitivities. The yellow shaded region indicates the NuFit 2016 $\sin^2\theta_{23}$ 90\% C.L. allowed region. |
