excited state column densities are wrong
smoke test at r9550 produces these column densities, which appear to be correct:
Hydrogen 1.249 4.301-12.117 (H2) Log10 Column density (cm^-2)
---
Carbon -5.094 -1.507 0.266 0.487 0.334 -2.455 -6.235
Nitrogen -5.875 -2.459 -0.346 0.053 -0.581 -1.724 -4.923 -9.062
Oxygen -5.076 -1.814 0.277 1.018 0.373 -0.876 -2.497 -6.344-30.000

We also report several excited-state column densities, which are mainly used to compare with ISM/IGM absorption line observations. These predictions end the block of predicted column densities:
{{{
Exc state He1* -3.175 CII*-35.930 C11*-35.930 C12*-35.930 C13*-35.930 O11*-35.930 O12*-35.930 O13*-35.930
Si2*-35.930 C30*-35.930 C31*-35.930 C32*-35.930
The He I column density is plausible but the others have hit some hardwired lower limit and are wrong.
The smoke test for c13_branch obtains reasonable predictions:
Exc state He1* -3.173 CII* -1.685 C11* -6.046 C12* -5.570 C13* -5.350 O11* -5.240 O12* -5.746 O13* -6.066
Si2* -2.673 C30* -4.134 C31* -8.319 C32* -3.960
