Docs: Fitting problems with IDL version of PAHFIT about pahfit HOT 6 OPEN

tau_Si>2 shows all sorts of "fitting problems" which may be more aptly described as "applicability of non-RT model problems" (e.g. ULIRGs). Information like this (not just looking back on the old PAHFIT, but general) could go under a well-advertised section on "Pitfalls and Warnings". This is where we can entreat users not to do stuff which is too stupid with science packs, and explain the limits of the model (some of which are TBD).

For 2 different spectra in the reflection nebula NGC2023: typically PAHFIT uses either the 200 K or 300 K component in combination with the 135 K component. This results in distinct dust-continuum intensities at the shorter wavelengths (5.5 um) and influences the intensities of the features perched on top.

Awesome plots. Would be great to have this as a section in the documentation. Don't stop posting here of course. But hopefully in the future you (or someone) will work up a doc page using rst to put this up at https://pahfit.readthedocs.io/. Happy to provide guidance on how to do this. All the content for the docs is in the docs/ directory.

I will look into that.

@els1 I'm not sure I'm interpreting your plot correctly. Blue is the fitted continuum under red, and green under black?

My apologies. Correct, the green is the PAHFIT fit to the black spectrum; the blue is the PAHFIT fit to the red spectrum.
