My senior thesis project involved a little bit of programming work on a FORTRAN 77 code that modeled emission lines from shocks. I cannot include that here because I only modified the code in a small way and did not write it; I don't believe it has been released under any completely free license.
My greater contribution was a script that modified the parameter file used as input for the shock model, ran the code, and extracted the relevant data. I created a database of a variety of line ratios corresponding to different temperature, density, and other physical conditions within a shock region (e.g. a Herbig Haro object).
Some samples of the results of my work:
Dominant [Fe II] lines for a variety of physical conditions
A sample Fe energy level diagram with numbers indicating the "line number" in the code.
A plot of the ratio of two lines for a variety of temperatures over a range of number densities.
This, and those below it, show the strongest lines and indirectly the line ratios at a given temperature for a range of number densities
