Comparison of Boltzmann‐averaged collisional de‐excitation rates. Dotted line: Rates from Burton et al. (1990). Solid line: Fit from Meudon code to the Martin & Mandy (1995) rates. Lower dashed line: Rate from Le Bourlot et al. (1999). Upper dashed line: Rate used in this paper, slightly modified from the Martin & Mandy (1995) fit. The point with error bars is the laboratory measurement of Heidner & Kasper (1972).
