How to use the JointFitter using excerpts from the notebook linked above is now in the astropy.modeling docs. https://docs.astropy.org/en/latest/modeling/jointfitter.html
Have not checked the speed issue yet.
Interesting. The size of the asymmetry is not easy to translate.
For where the modified Drude was taken from, see Eqs 4 and 5 in Gordon et al. (2021, https://ui.adsabs.harvard.edu/abs/2021ApJ...916...33G/abstract). Based on ideas given in https://www.sciencedirect.com/science/article/abs/pii/S0924203108000453?via%3Dihub. Check out this latter reference...

Ahh, yes. I see this now. Guess I didn't worry about this as it is a parameter that it is not clear has a physical interpretation. In your statement, what...
The fwhm is continuously changing in the modDrude equation. Not yet making the connection with your comments above between the asymmetry parameter and fwhm_o.
Maybe something with what you talk about above, but giving the fwhm blueward and redward at the half-max point?
Or maybe this would be best expressed as the red and blue hwhm?
