ball op• Data kinds: none → scalar (an op determined by its arguments alone — it takes no image or data input)
• Call: import fullseye as fs; fs.ledger.pendulum_period(L: 'float', g: 'float' = 9.81) -> 'float' (to call the implementation directly, import ballistics; ballistics.pendulum_period(L: 'float', g: 'float' = 9.81) -> 'float'; from the registry, opsdrive.get("pendulum_period"))

微小振幅の振り子の周期 2π√(L/g)。
• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).
• Operator provenance and references — the sources of the research/methods this op family came from.
• The canonical algorithm (author, year) and its uses are named in the family usage guide above.
