pressure (ArrayLike) – Surface pressure \(P\) of the measurement site.
latitude (ArrayLike) – Latitude of the site in degrees.
altitude (ArrayLike) – Altitude of the site in meters.
avogadro_constant (ArrayLike) – Avogadro’s number (molecules \(mol^{-1}\)).
n_s_function (Callable) – Air refraction index \(n_s\) computation method.
F_air_function (Callable) – \((6+3_p)/(6-7_p)\), the depolarisation term \(F(air)\) or King Factor computation method.
