ball op• Data kinds: signal → signal
• Call: import fullseye as fs; fs.ledger.magnus_lift_coefficient(spin_ratio) -> 'np.ndarray' (to call the implementation directly, import ballistics; ballistics.magnus_lift_coefficient(spin_ratio) -> 'np.ndarray'; from the registry, opsdrive.get("magnus_lift_coefficient"))
Lift coefficient C_L = 1 / (2 + 1/S) from the spin ratio S = rω/|v| (0 as S → 0, 0.5 as S → ∞; an empirical formula widely used in the ball literature).
• 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.
