Notes.In each section, the first line gives the integrated line intensities in erg s-1 cm-2 sr-1, the second line gives the ratio of the line-peak to line-center intensity, which is a measure of the line reversal (nr is used for “non-reversed” profiles), and the third line gives the line-center optical thickness of the 1D slab. The parameters p, T and D are, respectively, the gas pressure, kinetic temperature, and geometrical thickness, according to Table 1.
