 Reject a missing or negative pre-factor (mirrors the Python rate's validate; missing "A" leaves m_A as NaN, which the negative check alone would not catch since NaN < 0 is false).

Detailed Description

\[ k(T_e) = A \, T_e^{\,b} \, \exp\!\left(-\left(E_a/T_e\right)^2\right) \]

Modified Arrhenius in the electron temperature with the squared-ratio exponential characteristic of a Druyvesteyn EEDF; \( E_a \) is expressed in Kelvin so the exponent is dimensionless. Shares ElectronTemperatureData with the Janev rate (both need Te only).
