dipole_to_torque_fit — DRIVE tactorque op

• Data kinds: signal × signal → table

• Call: import fullseye as fs; fs.ledger.dipole_to_torque_fit(D, M) -> 'dict' (to call the implementation directly, import tactorque; tactorque.dipole_to_torque_fit(D, M) -> 'dict'; from the registry, opsdrive.get("dipole_to_torque_fit"))

Usage

Linear calibration between the series D (K,) of 1 dipole component and known moments M (K,) [N·m]: D ≈ k M (through the origin) and D ≈ k₁ M + b (with intercept). Returns k, R2 (coefficient of determination through the origin = 1 − SS_res/SS_tot), k1, b, R2_affine, rmse_M (residual RMS converted to M). Corresponds to the paper's calibration coefficient c = 1/k. Raises ValueError: K < 2, shapes differ, all M are equal.
