GalCraft is a flexible software to create mock IFS observations of the Milky Way and other hydrodynamical/N-body simulations. It is entirely written in Python3 and conducts all the procedures from inputting data and spectral templates to the output of IFS data cubes in `fits` format. 

The produced mock data cubes can be analyzed in the same way as real IFS observations by many methods, particularly codes like Voronoi binning ([Cappellari & Copin 2003](https://ui.adsabs.harvard.edu/abs/2003MNRAS.342..345C/abstract)), Penalized Pixel-Fitting (pPXF, [Cappellari & Emsellem 2004](https://ui.adsabs.harvard.edu/abs/2004PASP..116..138C/abstract); [Cappellari 2017](https://ui.adsabs.harvard.edu/abs/2017MNRAS.466..798C/abstract), [2023](https://ui.adsabs.harvard.edu/abs/2023MNRAS.526.3273C/abstract)), line-strength indices (e.g., [Worthey 1994](https://ui.adsabs.harvard.edu/abs/1994ApJS...95..107W/abstract); [Schiavon 2007](https://ui.adsabs.harvard.edu/abs/2007ApJS..171..146S/abstract); [Thomas et al. 2011](https://ui.adsabs.harvard.edu/abs/2011MNRAS.412.2183T/abstract); [Martín-Navarro et al. 2018](https://ui.adsabs.harvard.edu/abs/2018MNRAS.475.3700M/abstract)), or a combination of them (e.g., the GIST pipeline, [Bittner et al. 2019](https://ui.adsabs.harvard.edu/abs/2019A%26A...628A.117B/abstract)).

An elaborate, Python-native parallelization is implemented and tested on various machines from laptops to cluster scales.



## Installation

### Using pip

```
pip install GalCraft
```

### From the git repo

```
git clone https://github.com/purmortal/galcraft.git
cd galcraft
pip install .
```

## Example

Follow the commands below to download test kit:

```
wget https://github.com/purmortal/galcraft/archive/refs/heads/test_kit.zip
unzip test_kit.zip
cd galcraft-test_kit/tests/
```

Then generate your first mock data using GalCraft command:
```
GalCraft --config test_kit --default-dir configFiles/defaultDir
```

The data cubes are saved into `./output/test_kit/`

## Documentation
A detailed documentation of GalCraft will be available soon.
