Notes.

^(a)

Gas velocity varies across the shell in the H_C.

^(b)

d is the distance between the surface of the IR source and the inner part of the absorbing shell.

^(c)

Thickness of the absorbing shell relative to the radius of the IR source.

^(d)

Not constrained, because the v = 0 levels are radiatively pumped.
