![PyPI - Python Version](https://img.shields.io/pypi/pyversions/cortecs)

A Python package for decreasing the memory footprint of opacity functions. The primary functionality is compressing opacity functions with varying flexibility. Current methods include

- polynomial fitting

- PCA-based fitting

- neural network fitting

All fits are currently made in along the temperature and pressure axes.

Additionally, `cortecs` can chunk up opacity functions. The radiative transfer problem can often be cast as embarassingly parallel, so each chunk can be sent to a different CPU.

Installation instructions

-------------------------

`cortecs` can be installed via pip:

```bash

pip install cortecs

```

or conda:

```bash

conda install -c conda-forge cortecs

```

or from source:

```bash

git clone

cd cortecs

pip install -e .

```

To install from source with optional neural network support:

```bash

pip install -e .[neural_networks]

```
