NOvA 2024 official data release (26.61E20 neutrino + 12.5E20 antineutrino)

This data release corresponds to the Bayesian 2024 analysis of NOvA $\nu_e$ appearance and $\nu_{\mu}$ disappearance data, corresponding to analysis described in [https://doi.org/10.1103/x53y-2b86](https://doi.org/10.1103/x53y-2b86). Exposure: * neutrino-enhanced beam: 26.61E20 protons on target* antineutrino-enhanced beam: 12.5E20 protons on target ## Credible intervals Root files that begin with 'contours_' contain 2D credible interval conours in `TGraph` objects, with `axis_` objects corresponding to the 2D axis for the credible intervals. Key for decoding the file names and objects in these files: * **Filenames** are formatted as `contours__{NOvAOnly,RCDB1D,RCDB2D}_{conditional,nonconditional}.root`* `NOvAOnly`: No external oscillation constraints applied.* `RCDB1D`: 1D Reactor Constraint from DayaBay 2024 results applied to $\sin^2 2\theta_{13}$.* `RCDB2D`: 2D Reactor Constraint from DayaBay 2024 results applied to $\sin^2 2\theta_{13}$ and $\Delta m^2_{32}$.* `conditional`: Marginalized over each mass ordering separately.* `nonconditional`: Marginalized over both mass orderings simultaneously.* **Objects in the files** are named with a long common prefix, and separate suffices in a format: `<variable><variable>_{NO|IO|BO}_[cred_int_{060|06287|090|095|09545|099|09973}]`:* `<variable><variable>` are the variable name:- `dcp`: $\delta_{CP}$- `sindcp`: $\sin \delta_{CP}$- `ss2th13`: $\sin^2 2\theta_{13}$- `dm32`: $\Delta m^2_{32}$- `ssth23`: $\sin^2 \theta_{23}$- `J`: Jarlskog invariant* `NO`: Normal mass ordering* `IO`: Inverted mass ordering* `BO`: Both mass orderings* The number following `cred_int`, if present, indicates the fraction of the posterior contained by the credible region: 60% 68.27%, 90%, 95%, 95.45%, 99%, 99.73%* TGraphs corresponding to contours also contain a final numerical suffix differentiating disconnected components at the same contour level (All of the TGraphs that differ only by this final suffix should be plotted together to obtain the final contour).
