# Introduction

`solar` is a Python module that provides solar flux density from a variety of
models. These models are currently supported:

| Name       | Wavelength range (microns) |
| ---------- | -------------------------- |
| Colina     | 0.1195 to 2.5              |
| Kurucz     | 0.15 to 300                |
| Rieke      | 0.2 to 30                  |
| STIS       | 0.1195 to 2.7              |
| STIS_Rieke | 0.1195 to 30               |

`solar` is a product of the [PDS Ring-Moon Systems Node](https://pds-rings.seti.org).

# Installation

The `solar` module is available via the `rms-solar` package on PyPI and can be
installed with:

```sh
pip install rms-solar
```

# Getting Started

The `solar` module provides five functions:

- [`flux_density`](https://rms-solar.readthedocs.io/en/latest/module.html#solar.flux_density):
  Compute the flux density of a solar model in the specified units.
- [`bandpass_flux_density`](https://rms-solar.readthedocs.io/en/latest/module.html#solar.bandpass_flux_density):
  Compute the average solar flux density over a filter bandpass.
- [`mean_flux_density`](https://rms-solar.readthedocs.io/en/latest/module.html#solar.mean_flux_density):
  Compute average solar flux density over the bandpass of a "boxcar" filter.
- [`bandpass_f`](https://rms-solar.readthedocs.io/en/latest/module.html#solar.bandpass_f):
  Compute the solar F averaged over a filter bandpass.
- [`mean_f`](https://rms-solar.readthedocs.io/en/latest/module.html#solar.mean_f):
  Compute average solar F over the bandpass of a "boxcar" filter.

These functions take or return `Tabulation` objects. For more information on `Tabulation`
objects see the [`rms-tabulation`](https://github.com/SETI/rms-tabulation) package.

Details of each function are available in the [module documentation](https://rms-solar.readthedocs.io/en/latest/module.html).

Here is an example that plots the solar flux density for the visual range of 400
to 700 nm using the Rieke model at 2 AU in units of nm for wavelength and
W/m^2/nm for flux:

```python
import matplotlib.pyplot as plt
import solar

flux = solar.flux_density(model='rieke', xunits='nm', units='W/m^2/nm', solar_range=2)
flux = flux.clip(400, 700)
plt.plot(flux.x, flux.y)
plt.show()
```
