Underwater OCC Data at indoor tank and lake

Overview — This record contains the minimal dataset used to reproduce the key findings and figures of “centimeter‑accurate underwater ranging with a single LED and a single camera while conveying data”. It includes (i) frame‑level ranging logs for indoor tank and daylight lake experiments, (ii) per‑distance summary tables (including 8‑CSK performance), and (iii) a simple script to regenerate the main figures. Contentsdata/raw_logs/ — frame‑level CSV logs per distance and orientation (Diameter [px], estimated distance, ground truth, flags, exposure/gain).data/summary/ — per‑distance summaries for ranging and 8‑CSK (CSV).code/make_figs.py — script to recreate distance–estimate plots; code/requirements.txt. Reproducibility pip install -r code/requirements.txt python code/make_figs.py Output figures are written to figures/. Licensing — Data are released under CC BY 4.0. Custom analysis scripts are MIT‑licensed (see LICENSE_CODE.txt) and are included here solely for reproducibility. Funding — JST PRESTO (Grant No. JPMJPR2137). Contact — Corresponding author: [e-mail]
