+and its `cortecs` reconstruction. Note that opacities less than $10^-{60}$ are not generally relevant for the benchmark
 presented here; an opacity of $$\sigma_\lambda=10^-{60}$ would require a column nearly $10^{27}$m long to become
 optically thick at a pressure of 1 bar and temperature of 1000 K. \label{fig:example}](example_application.png)
