Save reproduce.py.txt as reproduce.py and kepler8-input.json in the same folder. Run:
python3 reproduce.py kepler8-input.json

Python 3 standard library only. Input dataset:15–2000 rows, BJD_TDB days, normalised relative flux and positive source error. The fixed template duration and ingress are assumptions. The returned profile interval is conditional, uses a 64-step scan per direction and is not a complete physical or systematic uncertainty. No network call, new observation, independent review, telescope request or discovery is performed.
