Lineshape Perturbation Function #49

Open eadkins333 opened 3 years ago

eadkins333 commented 3 years ago

An instrument lineshape function effectively redistributes expected absorption across a frequency range. The ability to include ILS in simulation and fitting is a recent MATS capability. Another potential perturbation between the model and observed spectrum could involve a perturbation to the absorption. alpha = nSg(v-v0), where n is the number density, S is the line intensity, and g is the lineshape. A perturbation on the absorbance could potentially be written as alpha = nSg(v-v0)(1 + BnSg(v-v0)), where B is a spectrum dependent parameter having to do with a non-linearity in the system.

This issue was actually introduced on 3/26/2020, but renumbered issues for consistency with the GitLab push
