Variable naming scheme?

### Description of improvement I'm new to the package, so perhaps this may have been discussed in the past. When reading over the code in a few places to look...

Two-photon calculation?

1

The calculation of the two-photon continuum does not seem to match the equation in the CHIANTI user's guide: As far as I can tell, the equation as programmed (in ChiantiPy...

Add `particlewise` keyword to `particle_collections.is_category`

8

## Description Addresses #2595 by adding the requested `particlewise` keyword to the function `particle_collections.is_category`. This changes the default behavior to return a `bool` rather than a `list` of `bool`. If...

Add continuum contributions to `IonCollection.radiative_loss`

2

Fixes #232 I've added f-f, f-b, and 2-p continuum emission to the radiative loss calculation. It appears to be working, but I'd like to do a bit more testing. One...

Substitute `.splups` files for `.scups` files in functions for older versions of the database

2

#17 had a note that the files will need to be substituted in any function that makes use of `.scups` datafiles. The tests would need to be suitably modified as...

Incorporate dielectronic ions into two-photon continuum

1

Once dielectronic ions are implemented (#269), they need to be added to the two-photon continuum. This may just be a matter of validating that it works correctly.

Type hints for functions

4

The return statements in functions in fiasco can be quite varied, both in terms of the units and the data types/structures. There are still a good number of functions without...

Add calculation of dielectronic level populations

2

I don't see another issue for this, so making a new one. [See the discussion here](https://github.com/wtbarnes/fiasco/pull/260#issuecomment-1958066757). Fiasco does not currently have a method to calculate level populations for a dielectronic...

Integrating non-Maxwellian distribution functions?

6

Currently there's an extension to CHIANTI called KAPPA (http://kappa.asu.cas.cz/) that recreates its IDL structure for various kappa distributions, with the same functionality otherwise. The ionization equilibria, etc, could presumably be...

Add a how-to guide in the docs showing how to rebuild of database

4

While working on #260, I had updated the units for the `hseq_2photon` parser (to remove units from `A_sum`). The database then requires a rebuild in order to correctly parse the...
