flight_fit — DRIVE ball op

• Data kinds: signal × points × table → table

• Call: import fullseye as fs; fs.ledger.flight_fit(t, p, omega, bp: 'dict', *, iters: 'int' = 12, dt: 'float' = 0.001) -> 'dict' (to call the implementation directly, import ballistics; ballistics.flight_fit(t, p, omega, bp: 'dict', *, iters: 'int' = 12, dt: 'float' = 0.001) -> 'dict'; from the registry, opsdrive.get("flight_fit"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

観測 (t_i, p_i)(跳ねを含まない区間)に、抗力 + マグヌス(ω 既知)の運動方程式を 初期状態 (p₀, v₀) の 6 パラメータ で

Gauss–Newton(有限差分のヤコビアン)で当てる。放物線の当てはめは抗力・マグヌスを g と v₀ に吸うので予測が曲がる —— こちらは

先駆者の「空力モデルつきの追跡」に当たる。返り値 `{"p0", "v0", "rms", "iters", "t0"}`(p₀・v₀ は t = t[0] での状態)。

真値の軌跡を入れると 1e-9 で戻る(門)。
