# BAM: Baryonic Abundance Matching
BAM implements a subhalo abundance matching model based on Yao-Yuan Mao's [implementation](https://github.com/yymao/abundancematching) with Peter Behroozi's fiducial deconvolution via the Richardson-Lucy algorithm.
Assumes a constant lognormal scatter in the galaxy proxy conditioned on the halo proxy. See the following example notebook: [``./tutorial/tutorial_SHAM.ipynb``](https://github.com/Richard-Sti/BAM/blob/master/tutorials/tutorial_SHAM.ipynb).
If you use or find helpful any of the code implemented inthis repository please cite [1].
## Installation
The best code is the one that can be *easily* tinkered with. Therefore, a direct pip-installation from PyPI is not supported. Instead, I suggest to clone the repository into your favourite folder:
```bash
cd /path/to/your/favouritefolder
git clone [email protected]:Richard-Sti/BAM.git
```
Furthermore, if needed the the code can be locally installed via pip:
```bash
cd /path/to/your/favouritefolder/BAM
pip install .
```
If locally installed the code can then be imported as usual:
```python
import BAM
```
