## Features

- Uses Tensorflow to emulate the following summary statistics: 21-cm power spectrum, 21-cm global brightness temperature, IGM spin temperature, and neutral fraction.
- Uses 21cmFAST to analytically calculate the UV luminosity functions and the Thomson optical depth to the CMB.

## Requirements

- Tensorflow >= 2.6
- 21cmFAST
