Incorporate alternative PAH decompositions.

This may already need to be updated for the ISO-SWS spectra due to its higher spectral R.

Does this mean different intrinsic shapes or just different wavelengths?

els1 commented 5 years ago

Both.

We will definitely need this for JWST. The canonical approach would be to add the minimum set of additional (likely narrower) dust features to well-reproduce the training data. E.g. the 7.7µm "Complex" consists of 3 "sub-features" at 7.42, 7.6, and 7.85µm. With a few sub-features of different widths, you can do a pretty good job reproducing a reasonable range of complex shape. Or did you mean something different?
