The package also includes limited functionality of other refractivity models. These are not as extensive, work only under standard atmospheric conditions, or over a limited wavelength range, compared to the Ciddor model.
Included are
| Model name | Function | Remarks |
| ---------- | -------- | ------- |
| Barrell & Sears (1939)| `BarrellAndSears()` |Outdated model, especially poor for short wavelengths.|
|Ciddor (1996)| `Ciddor()` |Only at standard atmosphere. CO2 density can be changed.|
|Edlen (1953)| `Edlen1953()` |Only at standard atmosphere. Function requires wavelength only.|
|Edlen (1966)| `Edlen1966()` |Only at standard atmosphere. Function requires wavelength only.|
|Owens (1967)| `Owens()` | - |
|Bonsch & Potulski (1998)| `BonschPotulski()` |Function does not include humidity|
|Birch & Downs (1994)| `BirchDowns()` |Only at standard atmosphere. Function requires wavelength only.|
|Peck & Reeder (1972)| `PeckReeder()` |Only at standard atmosphere. Function requires wavelength only.|
|Hohenkerk & Sinclair (1985)| `slalib()` |Only at standard atmosphere. Function requires wavelength only.|

The last function extracts the refractive index from the `pyslalib.sla_refro()` function and thus requires [pyslalib](https://pypi.org/project/pySLALIB/). This is an optional dependency for the setup of AstroAtmosphere.
