specie Derived Type

Relative Temperature ratio. $T_{ref}/T_{s}|_{\parallel}$

Relative Mass ratio. $m_{ref}/m_{s}$

Temperature Anisotropy. $T_{\perp}/T_{\parallel}_s$

Relative charge ratio. $q_{ref}/q_{s}$

Density Ratio. $n_{s}/n_{ref}$

Relative Drift, normalized to reference Alfven velocity $v_{drift}/v_{A,ref}$ with $v_{A,ref} = B/\sqrt{4 \pi n_{ref} m_{ref}}$.

Neutral-species collision frequency \nu_{n,s}/Omega_{ref} = n_0 \sigma \sqrt{T_{\parallel,s}/m_s}/Omega_{ref} where we define Kn^{-1}= n_0 \sigma \rho_{ref} allowing us to write \nu_{n,s}/\Omega_{ref} =

Note: this quantity is derived from Kn (a global parameter) and the other species parameters. The user does not input this value.
