Diffuse hydrogen gas within a galaxy may be assumed to follow a Maxwell distribution at temperature 106 K, while the temperature appropriate for the H gas in the inter-galactic space, following the same distribution, may be taken to be 104 K. The ratio of thermal broadening ΔvG / ΔvIG of the Lyman-α line from the H- atoms within the galaxy to that from the inter-galactic space is closest to
