T2K far-detector events, predictions and official contours extracted from figures (2023, 2025)
T2K: far-detector events, per-mode predictions (2025 release PDFs), CC1π⁺ data and official Δχ²/contours, extracted
Event-by-event far-detector kinematics from arXiv:2303.03222 (vector markers), per-sample / per-mode predictions from the vector PDFs of the 2025 release, the νμ CC1π⁺ data, and the official Δχ²(δCP) and (sin²θ23, Δm²32) contours of arXiv:2506.05889. Digitised / vector-extracted by the Newtrinos developers from published figures; scripts alongside the data.
Data card 3/11 sections
| Provenance | Extracted from the arXiv sources of 2303.03222 and 2506.05889 and the 2025 release PDFs with the scripts in the same folder (vector paths where available). |
|---|---|
| Validation | Checked against the published numbers / curves in the verification entries listed above. |
| Known limitations | Digitisation, not an official release; precision limited by the figure. The μ-like event figure covers E_rec < 3 GeV only; the (sin²θ23, Δm²32) contour figure is a raster image (digitised by colour, less precise). Per-mode totals match the release legends to ≤0.3 %. |
