(PDR). Specifically, this is my attempt at their Table 2 of paper 2, ApJ 291, p749. The case b command appears because the Lyman lines are vastly optically thick in this environment. If the command is removed the Lyman lines will be optically thin, which will result in fast fluorescent excitation of the (nearly totally neutral) hydrogen atom. // >>refer model pdr Tielens, A. G.
