Notes.
Collisional broadening by neutral hydrogen gives either the broadening cross section σ(v = 104 m s−1) in atomic units (
), with velocity parameter α (see text for more details), or if the value is negative and no α given, then the line width is given in the standard form logΓ/NH at T = 10 000 K, where Γ is the full-width at half maximum in rad s−1 and NH is in cm−3.
