Yes, and there's nothing wrong with including this equation if it helps
to clear things up. Just make sure you label the optical depth as that
of the reference line. If you want to, you can include an additional
equation showing the terms for other lines from the same ion, but it's
basically just the above times a Boltzmann factor times some oscillator
strength ratios and stimulated emission corrections, blah blah blah...
