In calculating the g‐factors in the tables, transitions within the ground state multiplet were ignored. This is a good approximation at altitudes below 350 km, as the neutral collision frequency is much greater than the einstein a coefficients (∼10 −3 s −1 ) for the magnetic dipole transitions between the levels of the ground state.
