Model Decomposition for Near- to Mid-Infrared Spectroscopy of Astronomical Sources
Here next step for #280. Aside from the change in the features table introduced by #283, the user-facing `Model` things are basically unchanged (unless users were "digging for the astropy...
A real ambiguity regarding the `Model` -> `Features` interface is what type of data is returned back into the `Features` table. The most principled approach is to return only _details...
https://github.com/PAHFIT/pahfit/blob/45d14975eababec1221af88fa5dad2e74661a726/pahfit/model.py#L330 Because of our "mixed" `f_nu` vs. `lambda` units, shifting to the rest frame requires _dividing_ the observed flux density by `(1+z)`, not multiplying by it. The way to see...
In our current design, the model details, fit settings and fit results are put together in the Model class. This brings some complexity with it: - We always have to...
@sarduval: The "Sara Profile" is what we call a `Drude * Gaussian` convolution, and is what instruments _really_ deliver. To ensure the science pack is a physical description of the...
Let's discuss here the logic of how multi-segment fitting can/will go, now that we have abstracted out `Fitter` and its spoon-feeding parent `Model`.
https://github.com/PAHFIT/pahfit/blob/96757a664fd47b54130458948f5b5b8ac604948b/pahfit/helpers.py#L35 This should read `resources.files("pahfit") / "packs" / "science" / packfile` (some systems use other dir separators).
[github.com/drvdputt/pahfit/tree/experimental ](https://github.com/drvdputt/pahfit/tree/experimental) has diverged quite far from master. But it is in working order, and I am actively using it for my science goals. There are many aspects which we...
See [this note](https://docs.astropy.org/en/stable/table/mixin_columns.html#quantity-and-qtable). As-is we can't take say, a power value from the `Features` table and use it directly in a unitful calculation (e.g. multiply by a solid angle and...
Currently, the rows corresponding to unused features are masked out, so that they are displayed as a row of "--" when model.features is shown in a notebook. (reminder: unused means...
