Individual parameter tests for three of the LAH model parameters. Each panel gives the completeness fraction f_C = 0.5 as a function of intrinsic line flux and wavelength for a commonly observed range of a given parameter’s values (shown by the colored curves), with the remaining five parameters held fixed at an average value. This demonstrates the variable contribution to the detectability each parameter can make, with γ changing the 50% detection point by only ∼0.05 dex in intrinsic flux, while the q and r_sC lead to average changes of 0.08 and 0.13 dex, respectively.
